• Implicit time-marching finite-difference methods for solving the two- and three-dimensional compressible Euler and Navier-Stokes equations are presented. The distinctive feature of these methods is to use the momentum equations of contravariant velocity components. By using such equations, accurate and easy treatments of the solid wall boundary condition are realized for the Euler equations, and simple treatments of the periodic boundary condition become possible for the impeller flows. The numerical methods are based on the Beam-Warming delta-form approximate-factorization scheme, and take into consideration of the diagonalization and the up-streaming by the theory of characteristics. The computations of turbulent flows are implemented by using the two-equation k-ε turbulence model with the law of the wall. Finally, some numerical results of transonic cascade flows are shown.
