Abstract

Higher-order boundary element methods are presented for time-dependent convective diffusion in two dimensions. The time-dependent convective diffusion free-space fundamental solutions are used to obtain the boundary integral formulation. Boundary element method solutions up to Peclet number 10⁴are obtained for an example problem of plume propagation. We investigate the convergence rate and accuracy of the higher-order boundary element formulations. An extremely high accuracy of the boundary element solutions for highly convective flows is demonstrated.
