Thesis: Optimization of a powder switching device for material efficiency in LMD

In cooperation with the Chair of Laser Technology LLT, the Fraunhofer Institute for Laser Technology ILT offers the opportunity to write a thesis.   Laser metal deposition (LMD) is an industrially established additive manufacturing process for producing complex components, which is used in the aerospace industry, among others. The cost-effectiveness of the process is largely determined by the consumption of the metallic powder material used. In this context, the ILT has developed a novel control concept for the powder-gas jet that enables the filler material to be diverted between the process area and a collection container with virtually no delay. The optimal design of such a fluidically controlled powder switch requires a fundamental understanding of the interactions of all design-related influencing factors, which will be developed in this work using computational fluid dynamics (CFD) simulations.     Be part of change You will design and build a test rig to quantitatively measure the performance of the powder switch You will model different geometric designs and perform CFD simulations to derive causal relationships You will validate the results of your simulations directly on the test rig, thereby optimizing the development process     What you contribute You are enrolled in mechanical engineering, CES, simulation sciences, process engineering, electrical engineering, physics, or a similar degree program You are known for your independent, organized, and structured approach to work Ideally, you have some practical experience in CFD simulation (e.g., Ansys Fluent) and CAD design, as well as a broad technical interest and manual dexterity   What we offer 👥 Team spirit: Creative, interdisciplinary environment with a motivated team, flat hierarchies, and an informal culture.🖥 Workplace: Excellent range of machines and equipment, as well as first-class office facilities.💪 Involvement: Practice-oriented thesis in an innovative applied research environment.🧘 Work-life balance: Benefit from flexible working hours based on trust.➕ Advantages: Opportunity to benefit from exciting corporate benefits.🚐 Getting there: Good transport connections, parking spaces directly in front of the institute, an e-charging station, and a parking garage.   The position is limited in duration until completion of the thesis.
