This paper presents measurements of mixture fraction and velocity in a well documented turbulent nonpremixed jet flame of hydrogen into a coflowing air stream. The measurements are obtained simultaneously with a combined laser Doppler velocimeter and laser Raman scattering apparatus. From these measurements the joint probability of velocity and mixture fraction is generated. From the joint probability, the correlations of velocity with scalars are deduced; as these correlations are directly related to the turbulent transport of momentum and of mass, their accurate prediction is a significant test of numerical models of turbulent reacting flows. As an example of such a test, model predictions of the correlation of velocity with mixture fraction are compared with these new measurements.
