Enhancement of the momentum interpolation method on non-staggered grids
A novel interpretation of the momentum interpolation method (MIM) is presented in this paper. A revised method using quadratic interpolating polynomials for the calculation of the cell-face velocities is proposed, The performance of the proposed method (referred to as QMIM) is examined and its application to the well-known lid-driven now in a square enclosure problem is tested. The computed results are compared with standard reported benchmark solutions for a wide range of flow conditions. The numerical experiments show clearly the superiority of the new approach over the original MIM, in terms of numerical accuracy, rate of convergence towards the grid-independent solution, and computational efficiency.
