Abstract

The purpose of the current work is to develop a solution method for incompressible Navier-Stokes equations, for both velocity and temperature fields, based on ARTIFICIAL COMPRESSIBILITY concept. The equations are discretized in Finite-Volume formulation, convective fluxes are calculated using a high-order characteristic-based Roe-like flux splitting method. For time-marching, 5th-order Runge-Kuta algorithm, because of its wide range of stability, is used. The formulation can be used for both steady and unsteady flows. The results for three different flux treatments are presented. The first one is a kind of averaging method and the second and third ones are first and second order methods developed by the authors. The method validation is performed by solving velocity and temperature fields over circular cylinder and ribbed surface, and comparing the results by data in literature which a reasonable agreement would exist. The CONVERGENCE RATE of the method shows a sensible reduction in iteration steps.
