自己組織化マップを用いた流れの可視化

抄録

In many cases, results of flow analysis are visualized by contour lines or contour color surfaces with prescribed values (or functions), or by markers indicating flow features such as vortices or shock waves. However, in the case of newly analyzed flow fields, or of complicated flow fields, we must not know what to visualize in advance. The present authors have been researching of the method automatically visualizing results of flow analysis, by classifying the flow and giving color to the flow by SOM (Self-Organizing Map). In this paper, the usefulness of the present approach to compressible flow analysis is discussed.
