Control of Boundary Layer Build-Up in an Impeller

The operation of the power producing engine is directly proportional to smooth and efficient compressor operation. The efficiency of an engine is directly related to the compression ratio of the compressor and expansion ratio of the turbine. So the need of understanding pressure loss due to low performance and poor reliability, slipping of flow is essential in today scenario. An investigation of flow over a centrifugal impeller is aimed to control the boundary layer build-up due to side slip of working fluid. For the purpose of flow analysis a CAD model of an impeller was designed using CATIA V5 and structural analysis has carried out for the designed model to check the maximum stress. As the main objective is being fluid flow analysis, the flow volume for the impeller model was generated using GAMBIT software and analysis was carried out using FLUENT.
