Your Mission
:

Re-entry represents one of the most technically demanding phases of any space mission as during this stage, a spacecraft must transition from the vacuum of space into the dense layers of Earth's atmosphere while traveling at hypersonic velocities. The complexity arises from the intricate interplay between fluid dynamics, thermal loads, structural integrity, and strict safety requirements.

A key aspect of the design process is the development of computational routines capable of analyzing shock wave formation, thermal flux distribution, and pressure fields to gain insight into the complex physical phenomena involved.

This thesis will primarily focus on the development of a CFD-based approach to address the re-entry problem for a reusable rocket upper stage, aiming to capture the key flow features and thermal loads experienced by re-entry vehicles through high-fidelity numerical simulations.

To achieve the target state, the following steps are foreseen:

• Develop a working knowledge of the main physical phenomenon that arises during re-entry
• Understand the capabilities of the various computational methods and their limitations (DSMC, Navier-Stokes, Panel methods, …)
• Develop a modelling approach and present it
• Keep detailed notes about the development of the methodology
• Develop a routine using open-source tools (such as SU2, OpenFOAM, SPARTA, etc) for the re-entry flow simulation

Your Story
:

• Currently enrolled in a Master in Mechanical-,or Aerospace Engineering
• Excellent knowledge of written and spoken English
• Engineering and scientific curiosity, proactive attitude
• Strong focus on fluid dynamics and CFD
• Familiar with simulation with open-source tools and Python scripting
• Good independence, team-working abilities and communication skills
