CALCULATIONS OF INCOMPRESSIBLE FLOW ON A STAGGERED TRIANGULAR GRID, PART II: APPLICATIONS

Abstract

In this article, applicability of the solution procedure on a staggered triangular grid is shown by solving several test problems. The computational results are also compared with those by other numerical analyses or available experimental data. It is shown that the proposed method is a feasible tool to calculate incompressible flow field with arbitrary boundaries. Meanwhile, several computational parameters in the solution procedure are considered to assess the numerical performance of the present formulation by soaring two more complicated problems. These computational parameters include a linear system equation solver, inner iteration number, and underrelaxation factors. From the numerical experiments, it is demonstrated that, with suitably chosen computational parameters, this suggested method is quite robust in solving incompressible flow over a wide range of Reynolds numbers.
