Master Thesis Modelling Leakage in a Rough Contact by Considering Multiscale Topography

JobsCloseBy Editorial Insights

Bosch is seeking a Master Thesis candidate to model leakage through rough contact with multiscale topography, focusing on an elastomer against steel in a static elastic state. You will review existing models, implement the most useful one for industrial application, compare it with Bosch’s internal tools and analytical multiscale equations, and derive surrogate models from simulation data. Ideal candidates are pursuing a Master in Computational Engineering, Physics, Numerical Mathematics, Industrial Mathematics, Mechanical Engineering or related fields with excellent grades, have hands-on experience in simulation and modelling, and basic Python and/or MATLAB skills. On-site presence in Renningen is required; fluent English and good German; enrollment at university mandatory; 6 months. Attach CV, transcript of records, examination regulations and, if indicated, a work and residence permit; contact Arshia Fatemi.

Job Description

Leakage is one of the important technological challenges in mechanical systems, dealing with various fluids ranging from water and lubricants to H2 under pressure. In this thesis we aim to model the leakage trough a rough contact of an elastomer against steels in a static elastic state. The issue is that the roughness has a multiscale nature ranging from micrometers to nanometers and the leakage might occur in different scales. For this aim, there are a range of methods and theories to calculate leakage in the literature.

• During your thesis you will provide a review of the existing models and implement the most useful one for industrial application.
• Consequently, you will compare the model with the internal contact mechanics tools at the company and with analytical multiscale equations in engineering applications.
• Finally, you will derive surrogate or meta models to predict the leakage based on simulation data with simplified equations. 

Qualifications

• Education: Master studies in the field of Computational Engineering, Physics, Numerical Mathematics, Industrial Mathematics, Mechanical Engineering or comparable with very good grades
• Experience and Knowledge: in simulation and mathematical modelling; first experience with Python and/or MATLAB
• Personality and Working Practice: you excel at structuring tasks independently and with discipline
• Work Routine: your on-site presence is required
• Languages: fluent in English and good in German

Additional Information

Start: according to prior agreement
Duration: 6 months

Requirement for this thesis is the enrollment at university. Please attach your CV, transcript of records, examination regulations and if indicated a valid work and residence permit.
