    초록 Combustor diffusers in aircraft engines are required to maintain stable and efficient combustion, to provide the turbine nozzles with an acceptable temperature profile as well as with sufficient cooling air and to minimize the total pressure losses. For advanced aircraft engines the faired diffuser concept is unattractive due to the performance deterioration under a wide range of operating conditions. Therefore, the modem aircraft engines incorporated a different type of combustor inlet with dump diffuser concept because it produces a stable flow pattern. Many experimental and numerical studies have been reported on diffuser flows with tremendous insight on critical flow features. Nevertheless, the design optimization of dump diffuser is still an emerging field in the modem aircraft industry. In this paper parametric studies have been carried out to examine the flow features through a straight-walled pre-diffuser with a dump. The numerical studies have been carried out with the help of a two-dimensional standard k-ε turbulence code.
