Abstract

The present Bachelor Thesis deals with the simulation of thermal fluid structure interaction, espacially with the recognition of boundary conditions between the solid and the fluid. The first part introduces the theoretical background of the finite volume and finite element methods, which are needed to solve the fluid flow and the structual analysis numerically. In addition, the k-e method for simulating turbulent flows and the transfinte interpolation for grid generation are presented. Afterwards, this work illustrates how these theories work together in the fluid structure interaction (FSI). When simulating an FSI, one has to consider the coupling technique. In this work, the weak coupling with a partition approach is applied to use the software FEAP1 for the structural part and FASTEST2 for the fluid flow. The coupling of these programs is provided by the software MpCCI3. Then the newly developed functions for recognising the boundary conditions automatically are introduced and explained. In the last part some complex simulations are presented validating the functionality.
