Abstract
The convergence and computational-speed of the C-HSMAC and SOLA methods were discussed and compared in detail. It was shown that only the diagonal elements in the pressure matrix are taken into account in the SOLA method, while the numerical solutions of the matrix equation are obtained in the C-HSMAC method. In addition, the iterative numerical procedures in the SOLA method are based on the classical Jacobi method, while a high-performance iterative method can be available to solve the pressure matrix in the C-HSMAC method. As a result of the computation of 3D cavity flows, it was confirmed that the computational performance of the C-HSMAC method is higher than that of the SOLA method.
