| Abstract: | The modeling method of viscous terms of Navier-Stokes equations using distributed viscous body forces was investigated.Then a fast calculation code for the three-dimensional(3-D)unsteady flow in turbomachine was developed,by solving 3-D unsteady Euler equations with the distributed viscous body force model.The code was used to simulate the unsteady flow in a two-stage compressor under circumferential total pressure inlet distortion,and the results were compared with Reynolds averaged Navier-Stokes(RANS) res... |
