This study presents, the effects of the performance for different diffuser angle has been investigated by CFD methods. The steady numerical simulation using k-omega turbulent model with frozen rotor interface was used for multistage MVC(Mechanical Vapor Compressor) simulation. In this simulation using four section zones and only single passage on each stage is considered to reduce the computational cost and time consuming. This study is just only focused on the effect of angle. From the simulation result shows a good understanding about the optimum angle condition even though using steady simulation.
