Turbulent Plane Jet Structure
Publication: Journal of Engineering Mechanics
Volume 110, Issue 10
Abstract
In the numerical modeling, solutions are highly subject to the boundary conditions that should mathematically represent as much physical phenomena as possible. However, in the predictions of a turbulent flow associated with a well‐developed turbulent plane jet, the currently insufficient similarity solutions of plane jet profiles cause so much trouble in the starting points that several test runs have to be performed in order to examine the exactness of the guessed profiles of some turbulence variables. In the present study, analytical solutions of the stream function, vorticity, shear stress, and viscosity are derived from Tollmein's solution for a plane turbulent jet. Mean‐while, a numerical study based on the two‐equation, turbulence model is used to examine this set of similarity solutions. Except for the eddy viscosity, good agreement is obtained between the numerical and analytic solutions. From the comparisons, there also results a simple modification to the analytic solution of the eddy viscosity profile.
