The Central Institute of Engineering, Electronics and Instrumentation (ZEA-2: Systems of Electronics) is a scientific and technical institute of the Forschungszentrum Jülich GmbH, which performs research and development projects in cooperation with the institutes of the Forschungszentrum and external partners. The focus of the work is the development of electronic and information technology system solutions in sensor technology and detector technology, signal and data processing, measurement technology as well as imaging and processing.
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 some parts of this system simple, well known models exist. However these partial models do not capture all properties which are required and we are interested in. The dynamical behavior of the oscillating aluminum surface which is indeed coupling all 20 actuators is the most important issue. For system optimizing the actuator system has to be modeled more detailed and precisely. Therefore we intend a finite elements multiphysics simulation using the COMSOL software
Starting off you will examine the mechanical setup of the actuator system and later also the electromagnetic part as base of your model. Based on these findings you will use COMSOL to build a model of the actuator system and simulate its dynamics. 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. You will also get in touch with collaborating partners from university. The final target of your work will primarily to improve control, but also to better plan heat management and various other potential improvements.
