An experimental study was made of the structure of the hydrogen 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 the application of the foward scattering LDV system. Laser Raman scattering was available to measure the temperature profile and the number density of oxygen as well as nitrogen mo1ecules. Flame temperature was determined from the measured results of the Stokes-Raman spectrum of nitrogen molecules subjected to irradiation of the Argon laser (488nm). The results showed that 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. The high temperature region was behind the jet axis where the number density of the oxygen molecule showed a minimum. The number density of the nitrogen molecule increased downstream along the axis.
