Abstract

Abstract A three-dimensional finite-volume calculation procedure for incompressible flows in complex geometries is presented. The scheme is based on the modified Rhie and Chow momentum interpolation method [1], in which the original scheme has been modified to employ the curvilinear covariant velocity components as cell face velocities to provide always a simple and diagonal dominant pressure or pressure correction equation. The coupling between the continuity equation and the momentum equations is effected using the SIMPLE algorithm. The present scheme is applied to test problems, and the results are compared with available experimental data and other numerical results.
