Evangelos Drossos: Parallel-in-Time Simulaion for Fluid Dynamics Using Lattice Boltzmann Methods

Lattice-Boltzmann methods can be used to model physical phenomena in the area of fluid dynamics. In this thesis, we examine a parallel-in-time method for Lattice-Boltzmann simulations based on the parareal algorithm. In this context a predictor-corrector scheme is used. In this scheme, results that are calculated on a grid at lower resolution are used to predict initial values for a solver running in parallel on a higher-resolution grid. Further, we investigate the conditions and required conversions for the coupling between two grids of different resolution and present some preliminary results of the coupled method.
