Analysis of turbulent free shear flow and heat transfer using the mixing length hypothesis
Abstract
The finite element method was used to develop a mathematical model of the transport equations that describe two-dimensional and axisymmetric free shear flows. The mixing length hypothesis is solved along with the basic transport equations in order to determine the velocity and temperature distributions in such flows; heat transfer in a plane turbulent mixing layer and heat and mass transfer in axisymmetric coflowing jets are discussed as examples. The analysis is based on the assumption that free shear flows exhibit a zero pressure gradient normal to the principal direction of flow.
