Simultaneous measurement of flow and temperature fields based on color image information

An image processing measurement system was developed to obtain simultaneously both the velocity and temperature distributions from the images of dynamic behavior of the thermal stratification, visualized by using liquid crystal tracers. The correlation method was used to obtain the velocity vector distributions. In addition, an algorism for color discrimination using RGB notation system was applied to the color images to obtain the temperature distributions. Consequently, the efficiency of this system was confirmed. (author)
