Abstract:
It is well known that MEMS based microfluidic devices operate in very low Reynolds number regime (Re < 1). Analysis and design of such microfluidic devices requires the solution of incompressible viscous fluid flow or incompressible Stokes equations. In this paper we present a new accelerated boundary-element method to rapidly solve the integral form of the Stokes equations. The computational complexity of the proposed approach is O(Nlog(N)), where N is the number of panels used to discretize the surface of the micromachined device.
