Visual Simulation of Turbulent Flow in Two-Dimensional Channel with Steps

Abstract

The recent great data processing speeds and memory capacity of computers have rendered possible numerical simulation of complicated turbulent flows. A numerical calculation system based on large eddy simulation is applied for the fully developed channel flow with turbulence promoters. Computational results are displayed using a microcomputer system supported by HITAC M280H system computer of University of Tokyo and animation of the flow is generated on a 16 mm film.
