Experimental Data on Turbulent Wall Jets: A Correlation of Existing Data

IN a recent article on the protection of refractories in steel‐making furnaces, Chesters et al. discussed the application to furnace design of jets blown over surfaces. The theory of the wall jet is given by Glauert, who mentions as typical examples the flow produced on the ground by the downward directed jet of a vertical take‐off aircraft, and the flow produced under certain circumstances in canal sections separated by a sluice. Jacob et al. and also Zerbe and Selna have reported experiments on wall jets which were carried out as background work to the general problems of ice and fog formation on the inside surface of aircraft windshields. Other experiments have been carried out by Förthmann and also by Sigalla and Painz in the Fluid Dynamics Section of the British Iron and Steel Research Association, Physics Department.
