Abstract
A new numerical method for the direct numerical simulation of particle flows is developed. The method is based on analytic solutions valid in the immediate neighborhood of the particles. By suitably exploiting these solutions it is possible to effectively ``remove'' the particle boundary from the calculation. This procedure leads to a great simplification of the computational domain and fast solvers can be used. It is found that the operation count grows linearly with the particle number. Some preliminary 3-D results for particles in potential and Stokes flow will be described, and an extension to finite Reynolds number is demonstrated for the 2-D case of a cylinder in a channel flow.
