Biofluid Simulation and Modeling


Imagine a human being made entirely of solid materials. Seems strange, right? Indeed, nearly all processes in living organisms take place in a liquid environment. Oxygen transport in blood, swimming of bacteria, or the stability of cell membranes are but a few examples for the importance of biofluids.


Simulations using the power of present-day supercomputers allow the investigation of many of these phenomena in enormous detail. Such simulations have become an indispensable tool in all areas of modern physics which - after proper validation through closely corresponding experiments - opens the path for theoretical modeling and eventually for a complete understanding of the involved phenomena. The large range of time and length scales occuring in biofluids motivates the use of continuum (Boundary-Integral), mesoscopic (Lattice-Boltzmann) as well as atomistic (Molecular Dynamics) methods within our group.


Out of the vast subject of biofluids, our current research interest focusses on three areas: drug delivery agents in blood flow, absorption of electromagnetic radiation in biological liquids and molecular dynamics of liquid organic solar cells.


Funding for the group through the Lichtenberg program of the Volkswagen Foundation is gratefully acknowledged. Our simulations are mainly run on the SuperMUC and JUROPA supercomputing systems.
