The aim of the diploma thesis was creating a decarbonisation model of lime, implementation the model into CFD tool ANSYS Fluent and to test the decarbonisation model in a model of a real reactor. The required model was based on assumptions for a Shrinking Core Model (SCM). The main objective of this work was the non-catalytic conversion of substances and the search for the most used mathematical models for calcination. The CFD calculation, the sensitivity analysis and the Fluente parametric study were used. Data on the composition of gas flow, temperature, pressure and mass flow of limestone p

The transition from inner to outer ballistics is a crucial part for the stability of the projectile. A projectile is mainly stabilized in two ways, with fins or by rotation. This work is limited to analyze a fin stabilized projectile. The launch of the projectile and the deployment of the fins are a quick process, therefore high forces and high temperatures will act the stability of the projectile.

Solar energy is one of a very few low-carbon energy technologies with the enormous potential to grow to a large scale. Currently, solar power is generated via the photovoltaic (PV) and concentrating solar power (CSP) technologies. The ability of CSPs to scale up renewable energy at the utility level, as well as to store energy for electrical power generation even under circumstances when the sun is not available (after sunset or on a cloudy day), makes this technology an attractive option for sustainable clean energy.

There is an ongoing interest in analyzing the flow characteristics of swimming fish. Biology has resulted in some very efficient motions and formulating these motions is of interest to engineers. One such theory was written by Dr. William Vorus and Dr. Brandon Taravella involving ideal efficiency. It is therefore interesting to test the calculations to see if it is possible to design a motion that can create thrust without necessarily creating vorticity.

Abstract:

Flameless combustion can be adopted as a low-emission combustion regime in the aviation sector, which is one of the biggest contributors to NOx emissions and is expected to grow in the near future. Nevertheless, several issues must be solved before any practical applications. Effective design procedure must deal with either combustion or heat transfer phenomena occurring at extremely low—temperature conditions. To this aim, experimental and numerical analyses focused on the characterization of fuel/oxidant behaviour are strongly needed and represent an essential step for further development.

In this Dissertation computational fluid dynamics (CFD) analysis of Impact Stilling Basin has been done by modelling in Ansys Fluent (R15.0) software. Six different Models namely M-I, M-II, M-III, M-IV, M-V and M-VI have been modelled by changing the distance between the Impact wall and basin inlet , by changing the gap between the basin floor and impact wall. The distance and gap have been calculated in terms of Equivalent diameter‘d’. Values of Turbulent Kinetic Energy, Velocity, Wall Shear Stress at Outlet and Energy losses (Kinetic Energy &Specific Energy) have been calculated and compared

Abstract:

ABSTRACT In this Dissertation, using ANSYS Fluent software (R14.5) computational fluid dynamics (CFD) analysis of 3D Rectangular Baffled Chamber is done. The Model consists of combination of vertical standing as well as hanging angled baffles. Flow patterns are taken into consideration. The dead zones and stream lines together with velocity vectors are analyzed of chamber by changing number of baffles in terms of spacing and the discharge coming into the chamber. In a finite volume, the numbers of chambers form 4 to 6 are increased by reducing the spacing in terms of width between them

Abstract:

abstract: Proton exchange membrane fuel cells (PEMFCs) run on pure hydrogen and oxygen (or air), producing electricity, water, and some heat. This makes PEMFC an attractive option for clean power generation. PEMFCs also operate at low temperature which makes them quick to start up and easy to handle. PEMFCs have several important limitations which must be overcome before commercial viability can be achieved. Active areas of research into making them commercially viable include reducing the cost, size and weight of fuel cells while also increasing their durability and performance. A growing a

Abstract:

Expansions in channel enable us to provide transition from a narrow to a considerably wide – section, which is important in the design of many hydraulic structures. In the transition, there is tendency of flow to separate from its diverging side walls and form turbulent eddies. This happens if the angle of divergence exceeds the limiting threshold value. This phenomenon leads to undesirable energy losses and erosion to the walls of the channel and also on the downstream side of the channel. Earlier, Researchers have done work on the optimization of horizontal shape of the transition so a

abstract: This study uses Computational Fluid Dynamics (CFD) modeling to analyze the dependence of wind power potential and turbulence intensity on aerodynamic design of a special type of building with a nuzzle-like gap at its rooftop. Numerical simulations using ANSYS Fluent are carried out to quantify the above-mentioned dependency due to three major geometric parameters of the building: (i) the height of the building, (ii) the depth of the roof-top gap, and (iii) the width of the roof-top gap. The height of the building is varied from 8 m to 24 m. Likewise, the gap depth is varied fro

Abstract:

Hydrokinetic energy is the energy of a water mass due to its flow. The greater the water velocity, the greater is the hydrokinetic energy it posesses. Hydrokinetic turbines are used to covert this kinetic energy to obtain electricity. Since the performance of these turbines played an important role in viability of hydrokinetic power generation projects hence different design parameters are studied to enhance its power generation capacity and performance. In this project torque and rotational speed of simple Savonius turbine are obtained at different speeds. The values of stream velocity

In the last few years, closed refrigeration equipment becomes more popular because its consumption is much lower compared to the open ones. The work of this study focuses on the analysis of the cold air flow that traverses the equipment, knowing the external conditions. For this purpose, CFD ANSYS Fluent program was used. This uses the finite volumes technique to solve the equations of conservation of mass, momentum and energy. In the first part of

Abstract:

A CFD simulation of a CFM56-3 combustor burning Jet-A and a 100% blend of biofuels, is performed. It is intended to evaluate the viability of these biofuels in a combustion point of view, by analysing the emissions and the energy extracted when burning these through ICAO's LTO cycle, so that these biofuels can be considered as a future civil aviation fuel. The three biofuels considered for this study were extracted from jatropha seeds, algae and sunflower. Due to the confidentiality that exits among GTE manufacturers, it is very difficult to obtain the blueprint of any given part of a GTE, and
