Computational Fluid Dynamics (CFD) is a research field which has experienced great improvement in the last decades and now represents a mature area of science and an established engineering tool for analyzing flow problems in continuum 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 behaviour 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.

During the past years, in my former Computational Microfluidics Group at the Technical University Munich, we have develop efficient Lagrangian particle-based software which can describe accurately micro-mesoscopic flow conditions. The modeling framework is based on a selective hierarchical particle approach using Brownian Dynamics (BD), Dissipative Particle Dynamics (DPD), Smoothed Particle Hydrodynamics (SPH) and Lagrangian Particle Tracking (LPT) methods.

Areas of applications include the analysis of micro/nano-particles suspended in complex liquids, viscoelastic fluids, dynamics of macromolecules in microfluidics geometries, elastic micro-turbulence, microrheology and flow of biological constituents.

Teaching

  • EG-161 Thermodynamics 1

    The aim of the module is to give an introduction to the laws of thermodynamics and the relevant properties thus providing an appreciation of energy conversion processes by covering the following topics: thermodynamic systems, properties of pure substances, liquids, gases and vapours, the first law of thermodynamics, the second law of thermodynamics, closed and open systems and entropy.

  • EGA336 Biomedical Flows in Physiology and Medical Devices

    This course focuses on the application of fluid mechanics to the modeling of biological systems and medical devices. This is particularlty relevant to understand the (patho)-physiology of the human body and for the development of medical equipment. The course aims to introduce the mathematical techniques used for the areas of blood flow in the human vasculature and airflow in the lungs. In addition, some relevant biological processes and associated diseases will be discussed and related back to the fluid mechanical observations.
