The temporal discretization is based on fixed number of dual time iterations. The stator-rotor coupling algorithm is described and the time step size issue is discussed. Numerical results for the case of compressible flow in high pressure turbine stage are compared with numerical results achieved by independent numerical method with different topology of computational grid, numerical flux as well as discretization.
