Modeling and analysis of conical exhaust diffuser
The exhaust diffuser of a liquid machine, like a gas turbine, recuperates static pressing factor by decelerating the stream and changing over active energy into pressure energy. Thus, it is a crucial part in the climate of a super machine and assumes a basic part in deciding the presentation of a su...

| description | The exhaust diffuser of a liquid machine, like a gas turbine, recuperates static pressing factor by decelerating the stream and changing over active energy into pressure energy. Thus, it is a crucial part in the climate of a super machine and assumes a basic part in deciding the presentation of a super machine. As a consequence, the fluid machine's efficiency can be enhanced if the diffuser design is optimized for optimal pressure recovery. Computational fluid dynamics (CFD) study was done on diffusers with various half cone angles, and the shape that provided the maximum pressure recovery was chosen based on the results. The diffuser was then built and tested with the ideal shape. CFD analysis to determine pressure drop, velocity, heat transfer coefficient, mass flow rate, and heat transfer rate for various conical exhaust diffusers (rectangular, circular, and hexagonal), conical exhaust diffuser models modeling using CREO parametric software, and analysis in ANSYS software for different conical exhaust diffusers (rectangular, circular, and hexagonal). CFD and thermal study of conical exhaust diffusers using ANSYS analysis modules. |
