Title: Momentum, heat and mass transfer rates in boundary flows.

Abstract: A modelling technique for simulating the time averaged properties in boundary flows has been formulated. The technique solves the time averaged equations representing conservation of momentum, mass and heat transfer with an approximate mathematical method; and makes use of an interactive scheme, involving manipulation of the mesh into which the flow is divided, to reduce errors from the mathematical method. This technique has been used to simulate the time averaged momentum, mass and heat transfer rates in a series of radial wall jet flows. It has been shown that the technique can predict- momentum, mass and heat transfer rates in flow situations similar to those commonly found in industry. However, accurate simulation of the turbulent transfer processes in a chemically reacting Methane, Carbon Monoxide and Oxygen flow was found to be impossible, because of deficiences in the reaction model. From these results it was deduced that to accurately simulate the transfer processes in complex flows, involving chemical or ionic reactions, a more sophisticated modelling technique should be constructed. It is recommended that this technique be based upon the exact turbulent transport equations.
