TIME-MEAN VELOCITY FIELD MEASUREMENT USING VISUALIZED FLOW IMAGES
RESUMO
Recent developments in flow field measurement by means of image analysis are impressive. The great advantages of these methods are noncontact measurement into fluid and also instantaneous measurement in extended wide region. However, for the measurement of time-mean velocity field in steady flow, the methods already proposed are not practical, because the huge velocity data obtained from image analysis should be treated.
In this report, several techniques for the direct measurement of time-mean velocity field by visualized flow images are investigated. Concerning the so-called spatial filtering method, the time-mean averaged contrast method, and also the zero-cross counting method, features, and possibility of practical usage are examined.
