Typical Test Case for the CFD Validation of Axial Compressors

축류압축기 CFD를 위한 대표적 Test Case

The comming of high speed computers with large memory size in recent years has allowed the practical development of codes which solve the Reynolds-averaged NAvier-Stokes (RANS) equations in three dimensions. Such codes are already used by the large engine manufacturers for the advanced design of some engine components. Different computational fluid dynamics approaches and turbulence models exist, and it seems essential today to establish their degree of validity for application to typical configurations in turbomachinery. In 1993 the Turbomachinery Committee of the IGTI of ASME has issued an open invitation to predict the flow details of an isolated transonic fan rotor called as NASA ROTOR 37. This paper reports this test case.
