Abstract

In this paper, we conduct a comprehensive numerical study of convective mass transport from rectangular cavities in low-Reynolds-number flows. The flow field is calculated by a high-order implementation of the boundary-integral method, while the convective diffusion equation is solved using the spectral-element method. Numerical convergence tests are presented showing the high precision of these algorithms. Physical results in the form of concentraton contours and local mass fluxes are presented for cavity aspect ratios from 1:1 to 4:1 and for Peclet numbers from 0 to 100,000. We investigate the effects of inlet flow profile and system boundaries on the velocity and concentration fields.
