Objectifs du cours
The development of µ-TAS, Lab-on-a-Chip-systems and micro-reactors used for bioanalytics and chemical processing relies on the extensive use of computational fluid dynamics (CFD) and mathematical modeling in general. Within the last years CFD tools have emerged to high-fidelity multi-physics simulation programs which allow for simultaneous simulations of various physicochemical phenomena. Starting from the governing equations and the derivation of the numerical models, micro fluidic problems are exemplarily solved and discussed step by step. The efficiency dependence on key input parameter is analyzed for selected advanced problems.
The course will provide a comprehensive overview of modeling and simulation techniques.
Public cible
The course is mainly intended for scientists, engineers and advanced students active in the field of micro system development. Furthermore, the course allows decision-makers to get deeper insight in the filed of simulation and enables them to reliably account the benefit, effort and costs of corresponding simulations.

Enseignant(s)
Dr Tobias Baier from IMM Mainz GmbH, Germany. Tobias Baier studied physics at the University of Heidelberg, Germany, where in 2002 he received his PhD for work on condensed matter and statistical physics under the guidance of Prof. Christof Wetterich. In 2003 he joined the simulation group at the ‘Institut für Mikrotechnik Mainz GmBH’ (IMM) and was later appointed head of the simulation group. Since 2009 he holds a permanent research position at the Technical University Darmstadt at the Center of Smart Interfaces (CSI), where he is a member of the group of Prof. Steffen Hardt. His work focuses around mathematical modelling in the fields of micro reaction technology and (bio-) fluidic devices where especially computational fluid dynamics (CFD) plays a vital role during the design. His main interests lie in the modelling of reaction systems, stochastic biological systems and statistical evaluation of data. Dr Baier has training experience as a tutor in physics courses.
Dr Friedhelm Schönfeld from IMM Mainz GmbH, Germany. Friedhelm Schönfeld studied physics at the University of Cologne, Germany, where he received his PhD in theoretical physics in 1999. In the same year he joined the ‘Fluidics and Simulation’ department of the ‘Institut für Mikrotechnik Mainz, GmbH’ (IMM). In 2008 Dr. Schönfeld got a full professorship for mathematics at the University of Applied Science Wiesbaden. His major work of activity is mathematical modelling especially computational fluid dynamics (CFD) in the framework of micro- and bio-fluidic applications. His research interests focus on multidisciplinary modelling comprising the simulation of free surface flows, mixing and transport phenomena, chemical reactions and electrokinetic flows. Dr Schönfeld is author or co-author of about 50 scientific papers, 5 patents/patent applications and has training experience by teaching courses for students and technical staff.
