OHB System AG in Bremen is looking for a

Intern (m/f/d): Propulsion (re-entry simulation capabilities)

Your Tasks

• Re-entry Simulation Enhancement using DSMC-CFD
• Coupling and TITAN Framework

The propulsion department from OHB is looking for an intern to support the development of advanced atmospheric re-entry simulation capabilities. The goal of the internship is to extend the current DSMC-based re-entry simulation chain through the integration of CFD solutions and the incorporation of the TITAN framework into the simulation process. The intern will be fully integrated into the Analysis team of the propulsion department. Current re-entry analyses rely on rarefied flow simulations to characterize high-altitude flight conditions. The internship will investigate hybrid CFD-DSMC methodologies to improve accuracy throughout the complete re-entry trajectory and establish an integrated workflow using the TITAN framework.

• Get introduced to the existing DSMC simulation workflow and TITAN framework
• Investigate CFD-DSMC coupling strategies for multi-regime atmospheric entry problems
• Implement interfaces between CFD solutions and DSMC simulations
• Integrate TITAN into the existing simulation chain
• Apply the methodology to representative spacecraft re-entry scenarios
• Perform verification and validation studies on selected test cases
• Document the developed workflow and analysis procedures

Your Qualifications

• You are an enrolled student (m/f/d), e. g. in aerospace technology, physics, electrical engineering, computer sciences, business administration or comparable studies
• First work experience such as successfully completed internships is desirable
• Previous experience or studies in CFD, DSMC, aerothermodynamics, or atmospheric re-entry modelling
• Experience with OpenFOAM, SPARTA, or similar simulation tools is appreciated
• Knowledge of numerical methods and high-speed flow physics is a plus
• Programming experience in Python and/or C++
• Ability to work independently and adapt to different technical topics
• Strong analytical and problem-solving skills
• Very good communication skills
• High proficiency in English as working language, both spoken and written
• Duration: minimum 5 months

We offer
