Abstract
A semianalytical prediction of the trajectory of a turbulent jet issuing at various angles to the horizontal into a crossflowing stream is presented. The predictive technique utilizes the basic conservation equations, in conjunction with idealizations instigated by experimentally observed jet behavior, to arrive at two-dimensional trajectories in either a uniform or a spatially variable mainstream crossflow. Comparisons of the predictions with available experimental data yield good agreement over a range of jet to crossflow velocity ratios of two to eighteen.
