Abstract

: The task of flow visualization is to make the process of trans- port phenomena visible. This can be done through experiments or by simulation (CFD). Flow visualization, based on simulation, is superior to flow measurement in that the physics in the entire flow field are retrieved. The advance of computing machines has led flow visualization based on CFD simulation to become an economical research and design tool. Introduction The progress in solving engineering problems by computational fluid dy- namics has been governed by economics and technology in the computer field. The accuracy of the simulation of the real life situation depends on the grid size and on the maximum number of the grid elements which are involved in the iteration process. To date, even mid-range workstations can handle 3d- grids at acceptable resolution of 100,000 volume elements. The physical data delivered by the solver comprises a few megab
