Joint probability density measurements in an axisymmetric parietal radial plane jet

A probability density function for the most likely velocity field in the flow issuing from an axisymmetric parietal jet is presented. The formulation was developed from hot-wire and X-wire measurements of the jet flow velocities, treated with an algorithm involving a 64 x 64 matrix.The Reynolds tensor terms were integrated from the inertial volume tensor. It is found that the fluctuating velocity vector is not identical to the average velocity orientation, although it does have a nonzero value. It is shown that the most probable velocity vector pattern, treated as most probable velocity streamlines, can be considered stable.
