Flow patterns developed by the inclined slot air jets, injected in a main air stream flowing at different velocities from 132.5--208 feet per second in a four0inch square duct, were studied from numerous pressure probe readings. Velocity profiles across the width of the duct at various positions were obtained from the readings on a recorder chart, given by the travelling probe. An elliptical shaped zone of air recirculation was indicated from the velocity readings at different points. Several correlations were obtained to preduct the area and the position of the zone of recirculation, when the fluid properties in the jet stream and the main stream are known. From the date obtained in this experiment, the similarity drawn between the jet fluid obstruction and the bluff-body obstruction, seemed to be somewhat questionable.
