Optimierung der Kernherstellung durch numerische Simulation
… is of main interest. With the use of a numerical simulation it should be possible to create the core box layouts for every geometry and size without previous time consuming experiments. The simulation presented in this work is based on the iterative solution of a two phase flow, in which the fluid …

Numerische Simulation nichtlinearer Aeroakustik bei kleinen Machzahlen
… mehr und mehr an Bedeutung. Bei einer direkten numerischen Simulation ergibt sich für kleine Machzahlen nicht nur ein steifes Differentialgleichungssystem, sondern die Unbekannten koppeln zusätzlich auf unterschiedlichen Skalen miteinander. Diese Multiskalenkopplung wird exemplarisch an Hand der …

Numerische Simulation des Wärmeübergangs in einer kryogenen Raketenbrennkammer
… was simulated by a fluid/structure interaction simulation in which only the energy equation was solved for the solid domain. In this investigation, the influence of three oxidizer/fuel-ratios (O/F) and three chamber pressures was analized with special focus on boundary layer effects in the …

Numerische Simulation der Strömung in Miniaturkreiselpumpen zur Blutförderung
New operation techniques on patients undergoing cardiovascular surgery or short-term ventricular assistance have lead to the development of a new generation of blood pumps with minimal size. This development is mainly focussed on hydraulic performance and biocompatibility. This thesis covers the …
