Abstract:
As the key feature size keeps shrinking down, inductively coupled plasma (ICP) has been widely used for etching. In this study, a commercial ICP etcher filled with Cl 2/ Ar mixture was simulated. The simulation was based on a commercial software CFD-ACE+, which is a multi-module solver. For the simulation part, CFD-ACE module was used for reactor scale and CFD-TOPO module was used for feature scale simulation. We have reached a reasonable agreement between the simulative and experimental results. Specifically, the different causes of sidewall bowing and microtrenching were discussed. We also analyzed the causes of special profile as trench width scaling down. Moreover, the agreement validates correctness of the chemistry mechanism, so it can be used as guidance for the process designing and manufacturing equipment improvement.

Abstract:
The main purpose of active flow control research is to develop a cost-effective technology that has the potential for inventive advances in aerodynamic performance and maneuvering compared to conventional approaches. It can be essential to thoroughly understand the flow characteristics of the formation and interaction of a synthetic jet with external crossflow before formulating a practicable active flow control strategy. In this study, the theoretical model used the transient three-dimensional conservation equations of mass and momentum for compressible, isothermal, turbulent flows. The motion of a movable membrane plate was also treated as the moving boundary by prescribing the displacement on the plate surface. The predictions by the computational fluid dynamics (CFD) code ACE+® were compared with measured transient phase-averaged velocities of Rumsey et al. for software validation. The CFD software ACE+® was utilized for numerical calculations to probe the time evolution of the development process of the synthetic jet and its interaction within a turbulent boundary layer flow for a complete actuation cycle.

Abstract:
Plasma etching technology is an indispensable processing method in the manufacturing process of semiconductor devices. Because of the high fluorine/carbon ratio of CF4, the CF4 gas is often used for etching SiO2. A commercial software ESI-CFD is used to simulate the process of plasma etching with an inductively coupled plasma model. For the simulation part, CFD-ACE is used to simulate the chamber, and CFD-TOPO is used to simulate the surface of the sample. The effects of chamber pressure, bias voltage and ICP power on the reactant particles were investigated, and the etching profiles of SiO2 were obtained. Simulation can be used to predict the effects of reaction conditions on the density, energy and angular distributions of reactant particles, which can play a good role in guiding the etching process.

Abstract:
The aerodynamic design of airflow passages in fuel injection systems can be significantly enhanced by the use of CFD analysis. Attempts to improve the efficiency of the fuel nozzle design process by using CFD analyses have generally been unsuccessful in the past due to the difficulties of modeling swirling flow in complex geometries. Some of the issues that have been obstacles to successful and timely analysis of fuel nozzle aerodynamics include grid generation, turbulence models, and definition of boundary conditions. This study attempts to address these obstacles and demonstrate a CFD methodology capable of modeling swirling flow within the internal air passages of fuel nozzles. The CFD code CFD-ACE was used for the analyses. Results of nonreacting analyses and comparison with experimental data are presented for three different fuel nozzles. The three nozzles have distinctly different designs (including axial and radial inflow swirlers) and thus demonstrate the flexibility of the design methodology. Particular emphasis is given to techniques involved in predicting the effective flow area (ACd) of the nozzles. Good agreement between CFD predictions of the ACd (made prior to experiments) and the measured ACd was obtained. Comparisons between predicted and measured velocity profiles also showed good agreement.

Abstract:
Annular centrifugal extractors (ACE), also called annular centrifugal contactors offer several advantages over the other conventional process equipment such as low hold-up, high process throughput, low residence time, low solvent inventory and high turn down ratio. The equipment provides a very high value of mass transfer coefficient and interfacial area in the annular zone because of the high level of power consumption per unit volume and separation inside the rotor due to the high g of centrifugal field. For the development of rational and reliable design procedures, it is important to understand the flow patterns in the mixer and settler zones. Computational Fluid Dynamics (CFD) has played a major role in the constant evolution and improvements of this device. During the past thirty years, a large number of investigators have undertaken CFD simulations. All these publications have been carefully and critically analyzed and a coherent picture of the present status has been presented in this review paper. Initially, review of the single phase studies in the annular region has been presented, followed by the separator region. In continuation, the two-phase CFD simulations involving liquid-liquid and gas-liquid flow in the annular as well as separator regions have been reviewed. Suggestions have been made for the future work for bridging the existing knowledge gaps. In particular, emphasis has been given to the application of CFD simulations for the design of this equipment.

Abstract:
The energy problem is getting increasingly serious. As such, unused energy recovery technology is crucial for environmental protection, which has been investigated extensively. Several methods have been developed to utilize scavenged energy from the environment, such as waste heat, solar energy, wind energy, and tides energy to convert into useful power. There is a new idea of piezoelectric jellyfish generator which combines the utilization of sea wave and vibration energy. When sea wave passes through the jellyfish, the wave causes the tentacles to vibrate. The tentacles is made of piezoelectric polymer which can convert the strain energy into electrical energy. This paper discusses about the piezoelectric jellyfish's tentacles being disturbed by wave in the sea. We employed the commercial CFD software CFD-ACE+ 2006 to simulate this phenomenon. The parameters including its tentacle length (L) and wave propagating function (Y) are studied which affect the piezoelectric jellyfish capacity to generate power.

Abstract:
CFD analyses of two benchmark, two-dimensional, sinusoidally oscillating, turbulent flows (one with zero mean and one with nonzero mean) at relatively large Reynolds and Keulegan-Carpenter numbers and relative current velocities, have been performed with CFD-ACE, a Favre-averaged Navier-Stokes (FANS) code. The primary purpose of the investigation was a critical assessment of the computational accuracy of time-dependent turbulent flows with large-scale unsteadiness. A number of turbulence models, including the standard k-ε, re-normalization group (RNG) based k-ε, and low-Reynolds number model have been employed. Among others, a second order in time, second order in space, second-level predictor-corrector finite-difference scheme has been used. The analysis produced the time-dependent in-line and transverse forces, the force coefficients, instantaneous velocity, vorticity, and pressure distributions, and streamlines. Representative results are compared with each other and with those obtained experimentally.

Dual-frequency capacitively coupled plasma (DF-CCP) etcher has become the mainstream in dielectric etcher. By building a 2D axisymmetric model of 300mm DF-CCP etcher in CFD-ACE+ software, plasma simulation experiments are carried out by orthogonal design. Then a process model based on simulation results is proposed to analysis influence of key process parameters including high frequency voltage, low frequency voltage, and chamber pressure and center/edge flow ratio on chamber plasma characteristics. Finally, to get high plasma uniformity and plasma density, process optimizations are carried out.

Differing with the traditional way to perform electroporation (EP) by using the DC electrical pulse, this paper proposes a new EP system by applying continuous DC voltages to generate proper EP electric field strengths utilizing the shape change of the channel. The fabrication of chip and set-up of system are clearly described and simulations also carried out utilizing CFD-ACE to study the electric field strength distribution and the time span when fluid passes through different electric field strengths. The fabrication of the proposed EP system is quite simple and low-cost.

Abstract The report summarizes the results of the numerical simulations of proton exchange membrane fuel cell (PEMFC) by computational fluid dynamic (CFD) software. The code employed is CFD-ACE+ developed by ESI-CFDRC Company. The purpose of the study is to assess the capabilities of CFD-ACE+ code in the simulations of PEMFC. The phenomena involved in the water and heat management of PEMFC are very complicated. The phenomena involved include the flow of multi-component and multi-phase fluid in an open channel and through porous media, the electrochemical reactions at catalyst layers, the evaporation and condensation of water, conduction and convection heat transfer. A three-dimension single cell PEMFC model is built and the input values of the physical and chemical parameters of PEMFC are collected from the literatures surveyed. The measured polarization curves of a PEMFC can be reproduced by the present simulations. The PEMFC simulation results of CFD-ACE+ are examined and discussed in detail to check the consistency of the simulated results. Sensitivity studies are performed. The parameters considered in the sensitivity studies are the direction of flow (co-flow and counter flow), the thermal conductivities of membrane-electrode assembly (MEA), the coefficient of the proton in the JANNAF method which calculates the enthalpy of the mix gases, the thermal boundary condition of fuel cell outer surface (constant temperature and convective). The result of the simulations demonstrated that CFD-ACE+ has the capabilities to simulate the hydrodynamic phenomena of PEMFC. However, the code does not provide enough output about liquid water flow in the channel and its distribution in the fuel cell. Key words: PEMFC, PEFC, CFDs, heat and water analytic.

Abstract:
This paper presents base approach and methodology for computational fluid dynamics (CFD) analysis of adaptive finger seals. Finger seals can be utilized to separate high (HP) and low pressure (LP) zones in high speed rotating shaft environment. Seal reduces axial leakage and typically consists of first and second rows of bristles (sticks), which are packed in the staggered arrangement. First row faces high pressure side and second row faces low pressure side. First row of sticks is used to close circumferential gaps between the bristles of the second row, thus forming air tight package. Second row sticks are made with pads, which ride on the thin layer of film and are (in theory) capable of adjusting radial clearance (film thickness) in response to shaft radial movements or to axial pressure fluctuations. Seal adaptivity will depend on its solid structural stiffness, and on fluid film damping and stiffness characteristics. These characteristics are calculated implicitly during the coupled FSI (fluid-structure interactions) simulations.

Abstract:
This paper presents computational study for a large diameter (216 mm) and small space ratios (S/D = 0.25 and 0.5) jet impingement flow. CFD-ACE code was used as the computational tools; the code was first validated by comparing its predictions with both CFD and experimental data from the literature. Then, the study was performed for two different Reynolds numbers: 7600, 17700 and two different space ratios: 0.25 and 0.5. Also two different turbulence models were utilized in this study: low Reynolds number turbulent k-ε and k-ω. The CFD results were compared with flow visualization results conducted at the University of Minnesota for the same configurations. The impact of choosing different inlet conditions on the CFD flow field was examined. The k-ε model showed greater sensitivity to the selection of the inlet conditions. Moreover, the k-ω model showed much better agreement with the experimental data than the k-ε model.

Abstract:
AlliedSignal’s F124 combustor is analyzed using CFD as part of an effort to improve the design of the combustor. A reduction of soot emissions, without negative impact on other performance features such as liner life and lean stability, was the primary objective. The existing F124 combustor (TFE1042) was modeled using the commercial CFD-ACE+ software package to validate the CFD results and provide a basis for comparison for the modified design. Two design of experiment (DOE) matrices of the redesigned combustor were analyzed using CFD modeling. The results of the CFD solutions led to the selection of two configurations for combustor rig experimental testing. The test configurations were selected based on CFD predicted trends for smoke, ignition, lean stability and pattern factor. Engine tests demonstrated a smoke number reduction from more than 40 to less than 10. Lean stability was degraded as a result of a leaner primary zone, but adequate lean stability margin was maintained.

Abstract:
A novel spacecraft, the Sample Collection for Investigation of Mars (SCIM), was proposed for the collection and return of atmospheric gas and dust samples from the martian atmosphere. The SCIM mission, part of NASA's Mars Exploration Strategy, would allow scientists to greatly enhance our understanding of Mars' water, climate, and geological evolution by studying the element and isotopic composition of the gas and dust. The SCIM spacecraft was proposed to collect its samples during a single high-speed pass through the martian atmosphere at an altitude of 37 km and return the samples back to earth. For the atmospheric gas sampling aspect the SCIM employs the Atmospheric Collection Experiment (ACE), a dual-component apparatus consisting of a passive and a cryogenic sorption gas collection system. Each of these systems possesses a collection vessel that is initially under high vacuum. At the time of entry into the martian atmosphere, valves on SCIM open and gas flows into the parallel-plumbed passive and cryogenic sorption gas collection systems. The passive system simply allows the incoming gas to fill an initially evacuated 1 Liter vessel. The cryogenic sorption system employs a Joule-Thompson cryocooler and sorption medium that initially condenses and captures the incoming gas. As the SCIM begins to exit the atmosphere isolation valves close and trap the gas samples in their collection systems for the return journey back to earth. The minimum SCIM mission goal was to collect 100 cm3 @STP(≈ 0.2 g) of martian atmospheric gas and the ACE was being designed to gather 1000 cm3 @STP (≈ 2.0 g) using both the passive and cryogenic systems. The volumes referred to above correspond to standard temperature and pressure on Earth (e.g., STP). The goals of this study were to prove the gas collection concepts mentioned above and develop the numerical and experimental tools to allow for the optimization of a flight worthy ACE. This paper discusses the design, analysis, and testing of a prototype ACE. First, more specific details on the design and testing methodology for the prototype are presented. Next, the development of a computational fluid dynamics (CFD) model is discussed. Finally, empirical pressure data from the prototype tests are used to assess the performances of the passive and cryogenic sorption gas collection systems and are compared to numerical pressure predictions to provide a benchmark for the CFD model. Results indicate that the prototype ACE is capable of meeting the design goal of 1000 cm3 @STP (2.0 g) of total gas collection.
