  • In order to explore the integrated design method of inlet/engine,a simulation method was developed to analyze the coupled calculation of inlet distortion and compressor. First, a full-passage body force model for compressor was built by using blade force extracted from Reynolds average Navier-Stokes (RANS) simulation results. Second, by adding the compressor body force model into the CFX software, the flat baffle inlet distortion coupled with compressor was simulated and analyzed. Comparing the simulation results with experimental results, the compressor body force model could simulate the strong coupling interactions between the compressor and the upstream distortion flow field. And the body force model could reduce almost two magnitudes of mesh numbers compared with the compressor full-passage RANS model.
