Master Thesis: COMSOL finite element simulation of magnetic flux in an actuator system for turbulence research

Advertising institute: ZEA-2 - Electronic Systems
Reference number: D059/2017, Physics, engineering, informatics, applied mathematics

As a partner in the DFG funded research group FOR 1779 "Active Drag Reduction via Wavy Surface Oscillations" the Central Institute of Engineering, Electronics and Analytics – Electronic Systems (ZEA-2) builds and optimizes a Lorentz force based actuator system for use in wind tunnel experiments. For parts of this system simplified, well known models exist. However these partial models do not capture all properties with enough details which are required for an overall system understanding. One very important issue is electromechanical efficiency. Because the setup is very compact to deliver precise, short wavelength running waves on an aluminum surface, heat dissipation and powering 20 actuators becomes a serious issue with low efficiency. For system optimizing the actuator system has to be modeled more detailed and precisely. Therefore we intend to introduce a finite elements multiphysics simulation using the COMSOL software.

Your task:
Starting off you will examine the magnetic flux through the actuator system. Based on these findings you will use COMSOL to build a model of the actuator system to simulate both magnetic flux in the current setup and planned improvements to the setup to optimize the flux for best power-to-force efficiency. This work will be closely aligned with a further master thesis on the topic “COMSOL finite element simulation of an electromechanical actuator system for turbulence research”.

You will closely work together with the project team of engineers and physicists for this challenging task of properly capturing the system behavior. The team will be able to quickly take over and evaluate any insights gained from your simulation. This will also in close contact with our collaborating partners from university.

The final target of your work will primarily be to improve efficiency in terms of electrical power-to-static force and force-to-weight ratios, but also to insert these findings in a more general model for better planning heat management and various other potential improvements. .

Your profile:

  • Master student in physics, engineering, informatics or applied mathematics
  • Background in physics simulations
  • Preferably experience with COMSOL and/or Matlab
  • Self-reliant

Our offer:

  • Help on getting familiar with the subject
  • Work on a model with existing physical counterpart for quick feedback
  • Collaborate with an experienced team of scientists
  • State of the art lab equipment and tools
