Abstract

This paper deals with nonlinear FVM approach based on different kinds of meshing (using grids- C,O,H ).Theory is utilized to obtain the convergence rate, CPU time, coefficient of drag, coefficient of lift, lift/drag of the airfoil(NACA-0012). The airfoil considered is studied with three different types of grids viz. O-grid, C-grid and H-grid and accordingly obtain the values of pressure, velocity and temperature. Airfoil is studied with two different flow regimes (i.e., 0.8M 1.2M). A Finite discretization is applied throughout the process in case of gridding. The computational method does not require any tuning of parameters. The solution obtained shows the good resolution of all flow phenomenon and are obtained by computational analysis.
