Abstract

Incompressible high-Reynolds-number flows are simulated by solving the Navier-Stokes equations. A finite-difference method with third-order upwinding are employed without using any turbulence model. Most of the computations have been carried out using Cartesian coordinates system. Multi-directional formulation is applied for improved accuracy. Validity of this method is discussed. Examples are presented to show the applicability of the present approach to variety of problems. For understanding computational results, visualizing is very important. In the present paper, computational results are visualized in many ways.
