| Abstract: | In this paper, the AUSM+ method and Spalart-Allmaras turbulence model are used in a in-house CFD code to simulate the three-dimensional viscouse internal flow fields. Two test cases for the transonic flow in Sajben convergent-divergent duct and the flow in the stator passage of NASA TP-3252 are simulated to verify the code. The results show that the CFD code can be used to simulate the internal complex internal flow fields with satisfactory accuracy. |
