A higher-resolution numerical method for simulating unsteady subsonic and transonic viscous flows through gas and steam turbine cascade channels in wet or steam condition was developed. The fundamental equations contain the compressible Navier-Stokes equations and the model equations for vapor and liquid phases. The classical condensation theory is implemented to model the nonequilibrium condensation. These equations are solved using the fourth-order accurate compact MUSCL TVD scheme and the maximum second-order implicit scheme.
