We can offer you the following tasksLifetime and thus the exchange interval is of major importance for aluminum compressor wheels of turbocharger. The reason for this is the temperature field of the compressor wheel resulting from high circumferential speeds and pressure ratios. The material temperatures in combination with the centrifugal forces arising from the rotational speed define the lifetime and thus the exchange interval. Therefore, a reliable lifetime prediction requires a precise prediction of the material temperatures. This work focuses the sensitivity of compressor wheel temperatures on geometrical parameters of the compressor stage and cooling system as well as the sensitivity on thermal boundary conditions of the simulation model.
Content of the work is:
CHT computations for evaluating compressor wheel temperaturesComparison of CHT computation results with available measurement data of compressor wheel material temperaturesNumerical investigation of the sensitivity of compressor wheel temperatures on selected geometry parameter (geometry of compressor wheel backside cavity)Application of AI methodes to develop surrogate models for temperature prediction You can help us with these qualifications Master's thesis in mechanical engineering or aerospace engineering or similarBasic knowledge in the field of heat transferExperience in CFD simulation (preferred with ANSYS CFX)Basic knowledge in turbomachinery is a plus Our benefits for youCanteen, meal allowance, accessibility, workplace health management, company doctor, gym, parking, good transport links, employee discounts, student network, women's network

Your professional homeEverllence headquarters in Augsburg were once the setting for the invention of the diesel engine, with which Rudolf Diesel declared war on the steam engine. Today, our primary mission is to overcome the challenges faced by the marine, energy and industrial sectors – not only to ensure our customers' success, but also to preserve our environment. From small increases in the efficiency of individual components, such as dual-fuel engines, exhaust gas treatment systems or software solutions, to major innovations at system level – every day, around 5,000 employees work at our site in the beautiful renaissance city of Augsburg to create a better future. You too can help us do that. We are the employer for you if you want to make a difference.
That is important to usIntegrity and Compliance are essential elements of our corporate culture.
