Task

The Institute of Thermal Turbomachinery (ITS) has been carrying out numerical simulations of multiphase flows using the grid-free Smoothed Particle Hydrodynamics (SPH) method for several years. The specially developed research code turboSPH is used, which is specifically designed for the analysis of fuel atomization in aircraft engine combustion chambers. This physically complex process is significantly influenced by the turbulence of the flow, which poses particular challenges for numerical modeling.

A frequently voiced criticism of the SPH method is its limited ability to adequately capture the characteristics of turbulent flows. However, in an earlier work at ITS, an approach was developed that places the SPH method in the context of large-scale simulation (LES). In this way, the fundamental suitability of the SPH method for predicting turbulent flows could be demonstrated, although the proof has so far been limited to simple test cases such as the Kolmogorov flow illustrated.

The aim of this master's thesis is to build on these results and investigate the application of the SPH method to more complex turbulent flows.

This thesis offers the opportunity to gain in-depth knowledge of fluid mechanics and the development of novel simulation methods.
