The formulation and boundary conditions of the governing equations with generalized curvilinear coordinates for room air flow are presented in the preceding paper of this study. Semi-implicit scheme about time integral of the equations is applied to the formulation, so that the momentum equations and Poisson equation interact with each other. Present paper describes the numerical technique to solve the simultaneous equations of the discrete dependent variables with SOR method. Some numerical examples of two-dimensional room air flow are analyzed with k-e model equations and are shown and compared with results using a staggered grid system based on orthogonal coordinates system. The conclution is that the present formulation gives reasonable results with high accuracy.
