摘要：
A mixed velocity-traction formulation is developed for the solution of exterior Stokes flow problems with rigid-body motion boundary conditions. The resulting integral equation is discretized with the qualocation method, which is shown to be more accurate than the more commonly used collocation method. The formulation is adopted for the analysis of the flow around complex micro structures. Examples demonstrate that the proposed technique is both accurate and well conditioned. (C) 2005 Elsevier Ltd.
