Abstract

Comparative visualization of data form idfferent sources provides useful presentations to highlight similarities or differences. Such methods have turned out to be valuable for comparing results from numerical flow simulation with images taken during windtunnel experiments. Comparative visualization does not necessarily require images with a high degree of similarly. However, in the cases shown here it proved advantageous to simulate the experimental visualization technique to a certain extent to ease the comparison. The experimental flow visualizastion technique represents the surface flow field with oil streaks. We visualized the numerical surface flow field using the spot noise technique. The flow data are pre-processed and the parameters of the spot noise texture are tuned to enhance similarly of the resulting images.
