Title:
The Plane Turbulent Wall Jet. Part 1: Jet Development and Friction Factor
Report Date:
1961-06-01
Abstract:
An investigation was made of the jet development, the velocity profiles, and the wall shearing stress in a two-dimensional, incompressible, turbulent wall jet. Experimental data concerning velocity profiles, decay of the maximum velocity and the jet growth are presented over greater ranges than previously available. The shearing stress, maximum velocity decay and jet thickness are predicted analytically by momentum-integral methods and the shear stress is measured experimentally by a hot-film technique. The hot-film values are checked by the wall shear stress computed from the measured velocity profiles. Velocity profiles, velocity decay, and jet thickness agree well with previous investigators and the wall shear stress measurements help to resolve a wide divergence between the experimental values of the other investigators.
