Abstract
In computation fluid dynamics visualization is a frequently used tool for data evaluation, understanding of flow characteristics, and qualitative comparison to flow visualizations originating from experiments. Building on an existing visualization software system, that allows for a careful selectijon of state- of-the-art visualization technique and some extensions, it became possible to present various features of the data in a single image. The visualizations show vortex position and rotation as well as skin-friction lines, experimental oil-flow traces, and shock-wave positions. By adding experimental flow visualization, a comparison between numerical simulation and wind-tunnel flow becomes possible up to a high level of detail. Since some of the underlying algorithms are nor yet described in detail in the visualization literature, some experiences gained from the implementation are illustrated.
