Directional investment casting processes involve complex interactions of various mechanisms of heat and mass thansfer in spatially complex domains and in the presence of a change of phase. In particular, the transfer of heat within the furnace occurs in the form of conduction, convection and radiation. This thesis addresses the development of computational techniques to simulate, at a macroscopic scale, such casting processes. In this study the conservation of heat energy within the casting is assumed to be maintained by conduction, accompanied by the release of latent heat energy during solidification. The overall state of the radiation in the furnace chamber is analysed in terms of the absorbed, emitted and reflected energies for each surface defining the geometry of the chamber. By applying a diffuse-grey approximation to these energies, an expression for the net flux for each surface is derived. 2014-07-31T11:21:14Z 2014-07-31T11:21:14Z 2002 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/5522 eng application/pdf Department of Mechanical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
