Abstract
We present a new algorithm for the simulation of polymer-laden flows in microscale environments. Our algorithm is based on a hybridisation of high-order accurate continuum and particle methods. The continuum algorithm provides the basic framework for high-performance computations to resolve device length and time scales. It is coupled to a new particle method with an optimised treatment of particle interactions such that the time step is on the level of the fluid continuum. We demonstrate our simulation capability on the flow of polymers in a contraction microchannel used for single-molecule detection.
