Abstract:
The key correlating traffic variable for modeling vehicle emissions has evolved from average speed to vehicle-specific power (VSP), and recently to operating mode as defined in Motor Vehicle Emission Simulator (MOVES). The analysis of operating mode and its distribution, however, requires a large amount of data and is time consuming and challenging. This paper attempts to build models between the operating mode distributions and the common traffic variable—average speed—to facilitate the emission estimation. Focusing on light-duty vehicles and unrestricted access roadways, a floating car surve

Abstract:
To estimate local emissions accurately, it is necessary to develop site-specific operating mode (OpMode) distributions from local vehicle activity data at the 1-second interval (field continuous data/field data). Nowadays, large amounts of vehicle activity data are collected for navigation or traffic state monitoring. However, these data are not at the 1-second interval, they are at 2-second interval and above, and named the sparse vehicle activity data/sparse data in the paper. These data cannot be used to develop local OpMode distributions. Thus, the purpose of this study is to investigate h

Vehicle-specific power (VSP) distributions, or operating mode (OpMode) distributions, are one of the most important parameters in VSP-based emission models, such as the motor vehicle emission simulator (MOVES) model. The collection of second-by-second vehicle activity data is required to develop facility- and speed-specific (FaSS) VSP distributions. This then raises the problem of how many trajectories are needed to develop FaSS VSP distributions for emission estimation.

Abstract:
Microgrids are clusters of distributed energy resources, energy storage systems and loads which are capable of operating in grid-connected as well as in offgrid modes. In the off-grid mode, the energy resources supply the demand while maintaining the voltage and frequency within acceptable limits whereas in the gridconnected mode, the energy resources supply the maximum or nominal power and the network voltage and frequency is maintained by the grid. This chapter first summarizes the structure and control principles of microgrids. It then briefly introduces the structures and control perspectives of distribution static compensators (DSTATCOMs). Finally, some applications of DSTATCOMs are discussed in microgrids. The introduced applications are power quality improvement due to the presence of nonlinear and unbalanced loads, voltage regulation and balancing, and interphase power circulation in the case of the presence of single-phase energy resources with unequal distribution amongst phases. Each application is illustrated by examples, realized in PSCAD/EMTDC.

The simulation of the forced convection heat transfer occurring in a microchannel heat sink with unitary circular flow and short distance heat transfer is presented. The temperature and velocity distributions of the coolant in the microchannels under the different flow rates were performed using the commercial FE software package [ANSYS]. The lowest flow rate satisfying the maximum operating temperature of the electronic device is 2ml/min with the input heat flux 25W/cm2. The temperature difference along flow direction in the lognitudinal channel with the transverse channel arrays is reduced c

Abstract:
A quasi-steady multi-mode heat-transfer model for boiler concentric-tube overfire air ports has been developed that predicts the effect of geometry, furnace heat source and heat sink temperatures, axial injector wall conduction, and coolant flow rate on the tube wall temperature distributions. The model imposes a radiation boundary condition at the outlet tip of the ports, which acts as a heat source. The model was validated using field data and showed that both the airflow distribution in the ports and tube diameter can be used to control the maximum tube wall temperature. This helps avoid tu

Abstract:
In developing a leak-before-break case for a component in a pressurized system, a key element is an estimation of the size of through-thickness crack that will give a measurable leakage under normal operating conditions, and this requires a knowledge of the crack opening area. In this context, the paper presents a simple derivation of an expression for the crack opening area associated with an isolated crack that is subjected to a general Mode I symmetric tensile stress distribution which could arise from a combination of applied and residual stresses. The paper also presents a simple derivati

Abstract:
The effect of diesel and biodiesel blends on particle size and number concentration distributions were studied in diesel engine under different operating conditions, including speeds, loads, and injection timing. The results showed that the engine load was more influential on particle size distribution than the engine speed. At the high load, diesel fuels produced mainly accumulation-mode particles, and at medium or lower load, diesel fuel produced more nuclei-mode particles. The injection timing had obviously influence on particle size distribution and number concentration. Advanced injection

The exhaust filtration analysis system (EFA) developed at the University of Wisconsin – Madison was used to perform micro-scale filtration experiments on cordierite filter samples using particulate matter (PM) generated by a spark-ignition direct injection (SIDI) engine fueled with gasoline. A scanning mobility particle sizer (SMPS) was used to characterize running conditions with four distinct particle size distributions (PSDs). The distributions selected differed in the relative number of accumulation versus nucleation mode particles. The SMPS and an engine exhaust particle sizer (EEPS) were

Abstract:
Computational fluid dynamics analysis of the exhaust gas flow distribution in the inlet ductwork of a combined cycle power plant has helped improve both emissions performance as well as lowering plant operating costs. The Turlock Irrigation District Almond Power plant had recently installed an upgraded gas turbine (GT), and replaced both CO oxidation and selective catalytic control (SCR) NOx control catalysts in order to withstand the higher exhaust temperatures of the new gas turbine. After the retrofits, both NOx and CO emissions were within Permitted limits, but were above expected values,

Abstract:
Regions of positive slope in the pressure-discharge characteristics are one of the major concerns in design and operation of centrifugal pumps, as they are limiting the admissible operating range to values above the critical discharge. The industrial pump turbine of specific speed ν = 0.42 (nq = 66 min−1) proposed as QNET-CFD test case TA6-04 shows a marked saddle in the energy-discharge characteristic associated to a sudden drop of efficiency versus discharge at part load. The pump-turbine consists of a shrouded impeller with five blades, a diffuser with 22 guide and stay vanes and a spiral c

Toluene fuel-tracer laser-induced fluorescence is employed to quantitatively measure the equivalence ratio distributions in the cylinder of a light-duty diesel engine operating in a low-temperature, high-EGR, and early-injection operating mode. Measurements are made in a non-combusting environment at crank angles capturing the mixture preparation period: from the start-of-injection through the onset of high-temperature heat release. Three horizontal planes are considered: within the clearance volume, the bowl rim region, and the lower bowl. Swirl ratio and injection pressure are varied indepen
