In the present study, a new one-equation-type coherent structure subgrid-scale model for compressible turbulent flows, which is needed on the large eddy simulation, was proposed. For the purpose of verifying the prediction ability by means of the present model, we calculated the direct numerical simulations for the turbulent compressible channel flows with the isothermal walls, those with the adiabatic wall, and the turbulent compressible flows through the square duct constituted by the four isothermal wall, and performed a priori and a posterior tests for the present model. From results of the above tests, we suggested that the present model can reproduce the DNS databases.
