Progress in the method of liquid temperature measurement is also helpful in the study on reactive fluid system. Two fluorescent dyes are dissolved in water and excited by one excitation laser sheet in the present study. The one of fluorescent dye has high temperature dependence and another has low temperature dependence. By this way, the ratio of two laser induced fluorescence gives two-dimensional temperature profile without influence of laser intensity fluctuation. Temperature profile when heated air heat up water through aluminum tube and temperature profile when heated air is injected into water as bubble are measured using the laser induced fluorescence ratio of Rhodamine 110 and Rhodamine B. The heating characteristics by two type of heat transfer are compared. The results show that more uniform temperature increase is able to be attained by heated bubble injection into water.
