• Experimental results are reported on effects of a wall boundary layer on a flow created by a round turbulent jet injected perpendicularly through a plane wall. The data show that the wall boundary layer contributes to the formation of a swirling flow downstream of the jet together with a predominant negative pressure near the downstream edge of the jet orifice,; jet spreads are controlled by the wall boundary layer thickness, δ, and ; velocity and total pressure along a jet center-line are expressed as simple functions of δ. A qualitative consideration on the basis of a vortex model of the flow field is also made on a mechnism, which brings about an increase in penetration of the jet into the cross flow with an increasing wall boundary layer thickness.
