Two kinds of laser diagnostic techniques, the Rayleigh scattering and Raman scattering methods, were used to measure the temperature of the flame which propagates spherically in a spherical combustion chamber. First, the temperature of a stoichiometric methane-air flame was measured by the Rayleigh scattering method and the results were compared with the calculated values. It was found that the measured result agreed well with the calculated one for the temperature of the flame just behind the flame front, but the measured temperature was quite low compared with the calculated value in the final period of the combustion. Next, the Raman scattering method was used to measure the temperature of stoichiometric methane-air and propane-air flames. In this case, agreement between the measured temperature and calculated one is good. It was shown that the Raman scattering method is suitable for the temperature measurement of propagating flames.
