This thesis examines the interactive simulation of indoor air flow using high-performance computers. Particular focus is given to thermal fluid flow, which can serve as a basis for comfort analysis. The dissertation begins by addressing the subject of Computational Steering before examining the Lattice-Boltzmann method as the basis for the computational fluid flow simulation. Another key aspect of this work is the visualization of the obtained data. Here, various issues, including the parallelization strategy which is necessary for the simulation is investigated.
Different optimization strategies for use with the high-performance computer Höchstleistungsrechner Bayern II are also examined and the performance of the simulation code tested using benchmark examples in various configurations.
Another key aspect of this work is the validation of the simulation code based on two clearly defined benchmark problems. Finally, two potential industrial application examples are shown.
