Motivation
Oblique detonation combustors (ODCs) represent a novel concept for high-speed propulsion systems due to their potential for near-constant-pressure combustion and high thermodynamic efficiency. Figure 1 shows a typical propulsion system and its simplification for a numerical investigation.

Objectives
The purpose of this work is the numerical simulation and investigation of an ODC with increasing levels of complexity using the high-fidelity in-house code ALPACA guided gy the following work packages:

1. Identification of a suitable geometry and simulation setup.
2. Simulation of premixed hydrogen air mixture.
3. Simulation of non-premixed hydrogen air mixture.
4. Simulation of liquid fuel atomization in an ODC geometry without combustion.
Starting points for work package 1 can be found in [1–3]. The employed CFD solver ALPACA is written in modern C++ and implements all required physical processes. However, for work packages 3 and 4 some minor boundary condition implementations might be necessary.

Take aways
• Work with state-of-the-art CFD solver
• Experience with HPC clusters
• Scientific working and writing
