In order to grasp the state of heat genelation from power cables laid in utility tunnels, we are studying about natural convection in horizontal double cylinders modeled after the utility tunnel. Thermally sensitive liquid crystals are usefull for experiments of the natulal convection. This report shows that an incidence angle of a ray from a slit and the suspension density of thermally sensitive liquid crystals in water were examined with image-processer in order that the colored video image of the themally sensitive liquid crystals was converted to temperature distribution. For application, the temperature distribution in horizontal double cylinders are measured.
