| Abstract: | A novel technique for measurement of temperature field was studied by using thermochromic liquid crystals. The technique was applied to measure the temperature distribution and temperature boundary layer of liquid in a stirred tank. Some of the experimental results with glycerin and PAM aqueous as the tested liquids were presented in this paper. The liquid crystal thermographic technique coupling with a digital image processing system provides a rapid and accurate method for temperature measurement. It is useful to describe the mixing and heat transport processes of liquid in stirred vessels. |
