Investigation on improving the capability of predicting separation in modified SST turbulence model

To verify and improve the capability of predicting separation, SST turbulence model was modified and applied to simulate separation flows. Firstly, starting from the property of subsonic, Reynolds stress simulation improvement and separation correction were used, some significant conclusions were reached from comparison. Secondly, based on hypersonic and supersonic, the modified model employed compressibility correction and simulated shock wave/boundary-layer interaction in transonic, supersonic and hypersonic. Finally, the results show that Reynolds stress simulation improvement and separation correction can improve the capability of predicting separation and suitable compressibility correction obviously improves the capability of prediction supersonic and hypersonic separation flow.
