Abstract

In this work, our proposed idea is based on using the Richardson Extrapolation (RE) method for predicting convergence the pth order solution on unstructured grids [1]. Practically, we want to analyze the variation the convergence order compared the solution accuracy numerically of the Control Volume Finite Element Method (CVFEMs) [2, 3]. To this effect, the proposed model a two-dimensional solving Navier-Stokes (NS) equations coupled with the energy equation, with an irregular domain using six cases different unstructured meshes. All the numerical results are presented and
discussed; they have been obtained from our code FORTRAN program.
