Abstract

The solution of transport problems using dual reciprocity boundary element A review H. Power, C.A. Brebbia Wessex Institute of Technology, Ashurst Lodge, Ashurst, South- ampton SO40 7AA Abstract This paper surveys the most relevant works on the solution of the transport equation by the use of the Dual Reciprocity Boundary Element technique (DRM-BEM). An evaluation is carried out on the numerical performance of three of the most popular DRM-BEM schemes A brief review of each method is presented, followed by a numerical application, for which the performance of each scheme is compared and evaluated. 1 Introduction The two-dimensional steady-state transport equation (convection- diffusion) including first-order reaction can be written in the form where v* = u*(z,%/) and Vy = Vy(x,y) are the components of the velocity vector v, D is the diffusion coefficient (assuming the medium is homoge- neous and iso
