An experimental study was made of the structure of the propane jet diffusion flame discharged normal to a free stream of air with a uniform velocity profile. The velocity profile in the flame was measured by application of the forward scattering LDV system. A gas chromatograph was available to measure the concentration profile of the major species in the flame. The results showed that the flame configuration were correlated well with the ratio of the discharging velocity of the propane jet to the air velocity. The transition from an eliptic to a crescent shape was observed in the contour of the constant velocity in the transverse cross section normal to the jet axis of the flame. A peak in the CO concentration profile was observed below the jet axis where the propane concentration showed a maximum, and above the location of minimum O_2 concentration. The CO_2 concentration profile had two peaks which bore a resemblance to the temperature profile.
