In order to establish an effective and accurate numerical method available for internal flows with transpiration in which large computational domain and local fine allocation of grid points are required, a finite-difference scheme based on a multigrid method combined with the quadratic upwind interpolation for convective kinematics (QUICK) was tested. SIMPLE was used as a smoother, and an alternating direction implicit (ADI) method was adopted to secure rapid and isotropic propagation of a change in a variable occurring at one grid point to its surroundings. Additionally, velocity correction was made so that the correct mass flow rate of fluid was secured at every streamwise grid point. Some detailed discussion is given to the obtained results, and the effectiveness of the present method is demonstrated.
