Summary
An experimental system for simultaneous, real-time, multi-point measurements of concentration and velocity along a line located in a turbulent flow field is described. Rayleigh light scattering provides the concentration measurements which are utilized to correct the outputs of a linear array of seven hot-wires to produce accurate velocity measurements. Examples of experimental results for an axisymmetric jet of propane entering a slow coflow of air are presented. It is shown that the measurements provide new insights into turbulent mixing behavior.
