VIRTUAL VEHICLE ist ein international erfolgreiches Forschungs- und Entwicklungszentrum für virtuelle Fahrzeugtechnologien. Wir beschäftigen uns mit zukünftigen Fahrzeugkonzepten und zukünftigen Entwicklungsprozessen. Aktuelle Entwicklungen im Bereich der Antriebe und Fahrerassistenzsysteme führen zu stark softwarebasierten Fahrzeugen (software-defined car) und erfordern daher ein Umdenken und neue Ansätze in der Fahrzeugentwicklung. Mit über 300 Mitarbeitern und Mitarbeiterinnen sind wir in Europa das größte Forschungszentrum für die virtuelle Fahrzeugentwicklung. Wir arbeiten an sicheren, umweltfreundlichen und leistbaren Fahrzeugen der Zukunft.

The EV and EV powertrains are of great demand these days. Thermal management and cooling of the EV powertrain com-ponents is one of the vital aspects. Electric motor (E-Motor) is the main component for this powertrain. This thesis would explore the various methods for cooling the E-Motor. Further, carrying out the intensive 3D CFD-thermal simulations and studying effective cooling methods to avoid any hot spot or critical temperature rise. A reduced order model of the E-motor would also be developed based on the 3D CFD thermal Simulation. This reduced order model would provide a basis of future thermal digital twins embedded into a system simulation framework.

Your Tasks

  • Literature review for the E-motor cooling methods.
  • 3D CFD-thermal simulation of the E-motor (Mesh-Simulation-Post processing).
  • Parametric study based on influential parameters.
  • Developing one simplified surrogate or reduced order model for 1D system simulation.
  • Documentation and Publication.

What we expect from you

  • Ongoing studies in electrical, mechanical engineering, mathematics, physics, or similar.
  • Interest in modelling and simulation of physical systems as well as the fundamental of numerics.
  • First contact with numerical modelling is desirable.
  • Strong motivation and self-determination way of working.

What we offer

  • Collaboration and contribution in an engaged, dynamic team
  • Interesting work in an international research center
  • Paid Thesis
  • Mentoring program for new employees’
  • Diverse sports and health activities regularly
  • Corporate Events
