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 twodimensional 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.
