Project Description


Project description:

We have developed a multi-component compressible flow solver (Finite-Volume, C++) that can handle shock waves efficiently and accurately. Using a level-set formulation to treat sharp interfaces and employing multi-resolution techniques, we can study complex shock-interface interactions. Additionally, we have implemented different state-of-the-art diffuse interface approaches. One goal of this project is to apply our framework to latest multiphase applications to evaluate and compare the performance of both numerical approaches. This task could serve as an interesting starting point for the PREP student to get in touch with a state-of-the-art scientific code framework in context of compressible flows.

Afterwards, depending on the skills and interest of the PREP student, we can arrange the project in several ways. Either the focus is on numerical modeling with implementation work (C++ code, high-performance computing, numerical method implementation) to extend the code capabilities, or we can also focus more on applications and investigate some advanced problem in detail. Such problems typically comprise additional physical effects, such as surface tension. One possible application could be to simulate a three-component problem of a shock wave interaction with a bubble inside a vessel. This topic is relevant for the understanding how vascular injury is initiated due to cavitation during the treatment of kidney stones by shock waves.
