A measurement system based on the color image processing has been developed to obtain simultaneously both temperature and velocity distributions in thermal flow fields, The thermal fluid motion is visualized by thermo sensing liquid crystal tracers and fine nylon tracer particles injected into the fluid. By using the developed color image analysis program, the R, G, B values obtained from the thermo capsules are trnasformed into the temperature, and the velocity vectors are extracted by tracking of the each nylon particle, simultaneously, This technique can be applied to analyse the dynamics behaviour of unsteady thermal fluid flows.
