Abstract
The purpose of this work is to develop a combined integral-transform finite-volumes solution to heat conduction problems in heterogeneous materials. The considered problem comprises steady two-dimensional heat conduction in a heterogeneous medium composed of a polymeric matrix with low thermal conductivity and a metallic filler with higher thermal conductivity. Dirichlet boundary conditions are applied at the top and bottom surfaces, while the remaining boundaries are kept insulated. The Generalized Integral Transform Technique combined with a second-order Finite Volumes scheme were used to develop a hybrid numerical-analytical solution to the problem, which was implemented in the Mathematica system. Convergence results of temperature at selected positions are then analysed, showing that with 40 terms in the series and 50 divisions in the FVM grid, an error of about 1% is assured.
