Parametric Study of Charging Inlet Diffuser Performance in Stratified Chilled Water Storage Tanks with Radial Diffusers: Part 1–Model Development and Validation
A computational fluid dynamics (CFD) model has been developed to simulate the flow and heat transfer near a lower radial inlet diffuser in a cylindrical stratified chilled water storage tank during charging. The model was used to perform parametric simulations of inlet diffuser performance in full-scale tanks during thermocline formation, from which first-order correlation relating thermal perf...
متن کاملEffect of Double Row Diffusers on Performance and Flow Field of a Centrifugal Compressor
The present paper reports measurements carried out in a centrifugal compressor equipped with double row of low solidity partial vane diffuser. Performance of the compressor is measured with three sets of double row diffusers with different radial spacing between the diffusers. From these measurements best configurations are identified and static pressures on the diffuser walls and probe measure...
متن کاملA New Approach for Inlet Diffuser of Automotive Catalytic Converter Considering Conversion Efficiency of Pollutants
The monolithic catalytic converter is still the main pollution control device for modern vehicles in order to reach the ever-increasing legislative demands for low emission standards. The catalytic converters require a large expansion from the exhaust pipe to the front face of the monolith. Unfortunately, packaging constraints often do not permit the use of long diffusers. Hence, flow separa...
متن کاملA Robust Design Methodology for Optimal Microscale Secondary Flow Control in Compact Inlet Diffusers
It is the purpose of this study to develop an economical Robust design methodology for micro-scale secondary flow control in compact inlet diffusers. To illustrate the potential of economical Robust Design methodology, two different mission strategies were considered for the subject inlet, namely (1) Maximum Performance, and (2) Maximum HCF Life Expectancy. The Maximum Performance mission maxim...
متن کاملParametric Study of Charging Inlet Diffuser Performance in Stratified Chilled Water Storage Tanks with Radial Diffusers: Part 2–Dimensional Analysis, Parametric Simulations and Simplified Model Development
A parametric study of the thermal performance during charging of a full-scale radial inlet diffuser in a cylindrical stratified chilled water storage tank was performed by applying factorial experimental theory to the results of simulations performed with a validated computational fluid dynamics (CFD) model. Part 1 describes the development and validation of the CFD model. Part 2 summarizes the...
