Unsteady three-dimensional transonic viscous flows through a gas turbine cascade channel are numerically investigated using the higher-resolution shock-vortex capturing method proposed by the authors. The higher-resolution both in space discretization and time integration enables us to obtain real flow characteristics in the 3-D gas turbine cascade. As numerical results, calculated unsteady 3-D vortical structures in the wake and at the corner are shown, and obtained unsteady flow patterns near the blade under on-and off-design conditions are compared with eath other.
