Unsteady free convective flow in an enclosure with a stepwise periodically varying side‐wall heat flux

P.H. Oosthuizen

Free convective flow in a square enclosure with one of the vertical walls heated and with the opposite vertical wall cooled to a uniform temperature, the remaining walls being…

Three‐dimensional flows over backward facing s.tif

C. Nonino, G. Comini, G. Croce

Three‐dimensional flows over backward facing s.tif are analysed by means of a finite element procedure, which shares many features with the SIMPLER method. In fact, given an…

Coupling heat conduction, radiation and convection in complex geometries

I. Rupp, C. Péniguel

In many industrial applications, convection radiation and conduction participate simultaneously to the heat transfers. A numerical approach able to cope with such problems has…

Finite element modelling of radiation in a nonparticipating medium coupled with conduction and convection heat transfer with moving boundaries

Jean‐Vincent Daurelle, René Occelli, Marc Jaeger

The radiation conduction coupling leads to particular problems due to computation time and high heat fluxes. Because of the hemispheric nature of the radiation, it is difficult to…

Solution of temperature field in DC cast aluminium alloy billet by the dual reciprocity boundary element method

Bozidar Sarler, Jure Mencinger

The axisymmetric steady‐state convective‐diffusive thermal field problem associated with direct‐chill, semi‐continuously cast billets has been solved using the dual reciprocity…

Modelling of heat transfer coupled with columnar dendritic growth in continuous casting of steel

M. M’Hamdi, H. Combeau, G. Lesoult

The general aim of this work is to calculate the extent of the equiaxed zone in continuously cast steel products. Free equiaxed grains can grow only in undercooled liquid regions…

Lewis‐Ransing correlation to optimally design the metal‐mould heat transfer

R.S. Ransing, R.W. Lewis, D.T. Gethin

Heat transfer across the metal‐mould interface has been modelled by a generalized equation referred to as the Lewis‐Ransing Correlation. It has been shown that the spatial as well…

Why you should consider object‐oriented programming techniques for finite element methods

J.T. Cross, I. Masters, R.W. Lewis

Object‐oriented programming, as an alternative to traditional, procedural programming methods for finite element analysis, is growing rapidly in importance as algorithms and…

Towards a formal theory of development/evolution and characterization of time discretized operators for heat transfer

Kumar K. Tamma, Xiangmin Zhou, Desong Sha

The time‐discretization process of transient equation systems is an important concern in computational heat transfer applications. As such, the present paper describes a formal…
