Dissipative particle dynamics

This thesis proves that realistic problems in microfluidics can be solved with Dissipative Particle Dynamics (DPD) and in fact that this method can be used as a supplementary tool in an engineering design process of constructing microfluidic devices. This work is presented in two parts. Part I deals with the simulation approach of fluid particle methods, the setting of appropriate pressure boundary conditions and their application to a microfluidic problem with aggregating microspheres. In Part II the parallelization approach and its performance is presented, including new algorithms to handle large numbers of different species efficiently, or to optimize the load balancing in heterogeneous simulation problems. As DPD and its extensions leave room for interpretations, and many authors have adapted it in different contexts, first a literature review is given in the introduction Chapter 1.
