An experimental study was conducted on the structure of a propane jet diffusion flame discharged normal to a free stream of air with uniform velocity profile. Attention was paid to the effect of the ambient gas motion on the structure of the flame. The temperature and velocity profiles in the flame were measured using a fine thermocouple and forward-scattering laser Doppler velocimeter, respectively. A gas chromatograph was provided to measure the concentration profile of the major species in the flame. A photographic observation was also made to determine the flame configuration. The results showed that the increase in the cross-flow velocity caused a kidney shape of the contours of constant axial component velocity, temperature and concentration in the transverse cross section normal to the jet axis of the flame.
