“…If the diagonal dominance for coefficient matrix of the pressurecorrection equation can be enhanced, it will be easier to get an accurate pressure correction, and the convergence of the algorithm is therefore improved. The method of choosing cell face velocities, as indicated by Lee and Chiu (1992) and Choi et al (1993aChoi et al ( , 1993b, is concerned with using physical covariant velocities instead of the widely used contravariant components at cell faces to derive``another'' pressure-correction equation. However, this method cannot enhance the diagonal dominance for the coefficient matrix of the equation, as the two pressure-correction equations are equivalent.…”

“…Furthermore, if we choose the components of physical covariant velocities, V i to calculate the convection at cell faces,``another'' pressure correction equation can be derived; this has been indicated by Karki and Patankar (1988a), Lee and Chiu (1992), and Choi et al (1993aChoi et al ( , 1993b. That is, according to equation (8) and Table I (11) and (12), we have:…”

“…They estimated the degree of the dependence of numerical solutions on the velocity underrelaxation factor and obtained a formulation of the momentum interpolation which is independent of the velocity underrelaxation factor for a converged solution in Cartesian co-ordinates. The momentum interpolation method has achieved great success and is now being widely used in a variety of fluid flow calculations [7][8][9].…”
