Emmy-Noether Microfluids Group

Computational Fluid Dynamics (CFD) is a research field, which has experienced great improvement in the last few decades and now represents a mature area of science and an established engineering tool for analyzing flow problems in continuum fluid and solid mechanics.
On the contrary, computational micro- and nano-fluidics is a considerably less developed area, which is concerned with fluid dynamic processes occurring in devices or flow configurations with minimum design length in the hundreds of micrometers or smaller. The behavior of fluids at these scales is quite different from that at the macroscopic level due to the presence of surface tension, non-Newtonian effects, wetting phenomena, Brownian diffusion and hydrodynamic interactions with immersed particles and microstructures. These microscopic effects cannot be generally represented using a classical homogeneous continuum framework and therefore there is a need to develop new analytical and numerical tools.

In our Microfluids Group funded via the DFG Emmy-Noether Research Programme we develop efficient Lagrangian particle-based software which can describe accurately micro-flow conditions. The modeling framework is based on selective hierarchical particle approach using Brownian Dynamics (BD), Dissipative Particle Dynamics (DPD) and Smoothed Particle Hydrodynamics (SPH) methods.
Areas of applications include the modeling of micro- nano-particles suspended in complex liquids, polymeric fluids, dynamics of macromolecules in microfluidics geometries, microscopic elastic turbulence, microrheology and biofluidics. The framework developed allows not only to approach complex physical problems from an analytical point of view which has a “per se” important academic relevance, but also it provides an ideal environment for the engineering design and validation on novel microfluidics technologies.
