A new implementation of the boundary element technique for time dependent pseudo-stationary heat transfer

Abstract

A new implementation of the boundary element method solution technique has been devised to investigate time-dependent heat transfer. This new approach has been applied to the problem of oscillatory heat transfer in an isolated fin. A comparison of the results with an existing analytical solution indicates that the boundary element technique developed in this paper is very efficient. Results are obtained for an aluminium fin over a wide range of heat transfer coefficients, fin dimensions and amplitude and frequency of the base temperature oscillation of the fin.
