AN EXPERIMENTAL INVESTIGATION OF THREE-DIMENSIONAL FREE MIXING IN INCOMPRESSIBLE, TURBULENT, FREE JETS.

Abstract

An experimental investigation of the bulk properties of turbulent, three-dimensional, incompressible, air jets issuing into a quiescent air ambient is presented. The jet orifices utilized included rectangular, elliptical, axisymmetric and triangular geometries. Experimental results of pertinent mean flow properties such as axis velocity decay, half-width growth, etc., are reported. The flow fields of such jets are found to be characterized by three distinct regions in the axis velocity decay. The results obtained lead to the conclusion that low-speed jets which originate from non-axisymmetric orifices decay to axisymmetry far downstream of the jet exit. (Author)
