초록

In this study, we have modeled a subsonic diffuser with rectangular prism and tried to investigate the influence of a turbulent wake flow by numerical simulation using computational fluid dynamics based on steady-state Navier-Stokes equation and standard k-ε model. A commercial CFD program, FLUENT, is used on the analysis. The turbulent wake is generated by a rectangular prism, which is installed at the diffuser. Flow Uniformity Showed the best results in the case of AR=1:1 and tended to be uniform in the critical point at Re=8.8×103
