Abstract

Recent developments in heat transfer and porous media R.W. Lewis, J.T. Cross, D.T. Gethin, R.S. Ransing, M.T. Manzari & N.A. Rahman Department of Mechanical Engineering, University of Wales, Swansea SA28PP, UK Email: r.w.lewis@swansea.ac.uk Summary The paper describes some of the recent development made in finite element methods in heat transfer in our research group in Swansea. The paper is split into two sections: numerical optimisation and heat and mass transfer. The numerical optimisation section reports the results of two lines of enquiry, one based on the metal-mould interface coefficient and one based on casting and feeder shape, both driven by a desire to improve our ability to simulate casting. The second section describes recent improvements to models used to simulate the movement of heat, fluid and pollutants through deforming porous media, aimed at modelling the contamination of groundwater by petroleum hydrocarbons. Examples are given of simulations of all three area
