Abstract: It has been widely observed that a three-dimensional wall-jet has a large rate of spread in the direction parallel to the wall and a small rate in the direction perpendicular to it. Some observations of the more general case of a jet flowing along the intersecting line of two planes reveal the same spreading along the plane. Measurements of the volume flux in a buoyant jet show that the change in cross-section is accompanied by an increase in entrainment rate but the effect is small. In most cases the increase is masked by the decrease produced by a change in the turbulent field.
