Summary

A visualization method — syncronous visualization of flow patterns and correlative physical parameters is introduced. By the principle of image composition the image of flow patterns taken by video cameras and the image representing correlative physical parameters can be combined in composite image which can not only shows the flow patterns at some moment but also can shows syncronously the correlative physical parameters, such as vortisity, shear stress, pressure, force, moment, temperature and concentration etc. It is very useful for researching unsteady flow. As an example, the patterns of a flow past a two dimensional H-shape cross-section and the pitching moment acting on the H-shape cylinder are visualized syncronously. The results show a strong correlation between vortex shedding and fluctuating pitching moment.
