Instantaneous and simultaneous measurements of two-dimensional mixing behavior of air and fuel and temperature distributions were conducted by combining acetone LIF and Rayleigh scattering methods. This technique was applied to a partially premixed turbulent flame of CH4/N2 fuel using a single pulse and a 266 nm beam of Nd:YAG laser. The measured fuel concentration distribution corresponds to the temperature profile in each reaction zone. That is a useful way of investigating characteristics of the reaction zone. Comparing the measured results and the CH4 concentration which is derived by assuming to mix fuel and air homogeneously and the adiabatic flame temperature in chemical equilibrium, we cleared the validity of the measurement method.
