NUMERICAL ANALYSIS OF CONVECTION‐DIFFUSION PROBLEMS USING THE BOUNDARY ELEMENT METHOD

Abstract

This paper presents a boundary element formulation for transient convection‐diffusion problems employing the fundamental solution of the corresponding steady‐state equation with constant coefficients and a dual reciprocity approximation. The formulation allows the mathematical problem to be described in terms of boundary values only. Numerical results show that the BEM does not present oscillations or damping of the wave front as appear in other numerical techniques.
