The exhaust diffuser of a fluid machine such as a gas turbine recovers static pressure by decelerating theflow and converting kinetic energy into pressure energy. It is hence a critical component in a turbo machine environmentand plays a pivotal role in determining the performance of a turbo machine. Therefore, if the diffuser design is optimizedfor maximum pressure recovery, an increase in efficiency of the fluid machine can be brought about.The analysis is carried out for various models such as circular, square and hexagonal diffusers. The modeling isdone in Creo Parametric 3.0, thermal analysis is done in Ansys 15.0 and Flow Analysis is carried out in Fluent15.0(Workbench 15.0). The thermal analysis is performed to check for the better material which can be used to theDiffuser in order to increase the performance. Computational fluid dynamics (CFD) analysis was performed on diffusersWith different shapes and based on the results obtained the geometry that yielded the maximum pressure recovery wasidentified.
