Abstract
Simultaneous measurement of temperature and velocity in a three-dimensional flow field is carried out by using liquid crystal visualization combined with scanning light sheet technique. In order to obtain the temperature from the visualized color image, the spline fitting technique in a HSI color space is proposed for the color to temperature transformation and is applied to various points over the image plane to consider the viewing angle effect. The velocity distributions are analyzed from the intensity distributions of the two images illuminated by the two light sheets which are captured at the same position but with small time interval. This technique is applied to the study of thermal convection over a heated surface and the mechanism of thermal structures generated over the bottom boundaries are discussed.
