Abstract:

We have developed a novel algorithm for the simulation of polymer-laden flows in microfluidic devices. Our algorithm is based on a hybridization of high order accurate continuum and particle methods. The continuum method provides the basic framework for high performance computing of device length and time scales. It is coupled to a new particle method with an optimized treatment of particle interactions such that the time step is on the level of the fluid continuum. We demonstrate the separation of DNA strands in a microfluidic entropic trap.
