Inhalt:

In natural and constructed microsystems, unfamiliar physics of the fluid flow have been discovered and utilized. In this course, we give an theoretical basis of micro fluid dynamics and show example studies from the literature and conducted at the institute of fluid mechanics (LSTM-Erlangen). In the theoretical part, the fluid models for gases and liquids are discussed, The validity of the Navier Stokes equations is questioned by checking the continuum hypothesis. Different regimes of fluid flow are presented based on continuum considerations. Intermolecular, intramolecular, surface as well as well as particle forces dominating in micro fluid devices are discussed. An overview of modeling strategies on molecular, meso and macro scale is given. Prominent examples and studies from the literature are presented regarding the micro fluid dynamics. Example studies conducted at LSTM-Erlangen are presented. The students are expected to to understand the multiscaling and multiphysical nature flow phenomena in microsystems. The dominating forces in those systems will be made familiar to students. They should be able to conduct basic dimensional analysis to classify the flow with respect to the different flow regimes regarding the continuum hypothesis. Ultimately, they can decide which forces can be effective under certain gas, liquid and particle laden flows in Microsystems and which numerical modeling strategy is appropriate for a given microsystem. With the given applied examples from the literature and from our institute, it expected that students can establish the bridge between theory and application of the subject matter.
