Welcome to my website, where I share content related to my research on modeling, design, and analysis of compact turbines with both subsonic and supersonic flow.
Already at an early stage of my studies, I focused on complex aerothermodynamics of internal flows and turbomachinery, which quickly became my joy. In an internship and over the time of my Bachelor's thesis and Master's thesis I gained practical experience in the numerical simulation of compressor aerodynamics by means of CFD. At the end of 2013, I graduated with a Master's degree in turbomachinery and propulsion from the RWTH. During the period of my Ph.D. and an engagement as a postdoctoral researcher at the Universitat Politecnica de Valencia, Spain, I became an expert in radial turbine aerodynamics. Over the last years, I was able to profound my knowledge in CFD and was able to achieve advancements in the field of turbocharger turbine measurement methods and in the fields of one-dimensional modeling of radial turbine tip leakage flow and overall radial turbine performance. During an only four months lasting research stay at Purdue University, I was able to demonstrate the efficient use of my skills in a new working environment and on a different research topic. With the symbiotically matching know-how of the research group, the development of a novel kind of supersonic radial turbine and the registration of a provisional design patent was achieved in a very short time. With the acquired knowledge, I proposed a project together with TU Berlin and Purdue University to the European Commission and achieved the funding of our ROTRANS project as a Marie Curie Global Fellowship.
As a child, I could never imagine living abroad, although I always felt an inherent curiosity for different cultures. Then when I graduated from RWTH Aachen, I had the desire for continuous learning not only professionally but also in private, which pushed me towards the decision to do a Ph.D. abroad. A variety of reasons made me accept a position in Valencia, Spain. It was a professionally as well as personally truly enriching experience, even more than I could ever imagine before. Now, I see no other way than continuing on this path. Pushing for new technologies, while getting to know new places, languages, and people has become my passion. In the coming two years, I will be conducting research in the US. Following, I will move to Germany for one year to finish my Marie Curie Global Fellowship. Although this is my home country, it will be an international experience for me, after living for 8 years abroad. Definitely, I will be able to see the life in Germany from another perspective.
Aerothermodynamic modeling of turbomachinery requires a combination of creativity, engineering know-how, and mathematical knowledge and it is a great way to take advantage of my skillset. It is exciting to see how complex phenomena can be modeled with simplified models. Indeed, first comes a deep understanding of the complex phenomena and understanding of leading dynamics. A very help tool can be carefully executed Computational Fluid Dynamics simulations. Also here I like to dig deeper and deeper into the data and to distinguish leading phenomena from less important phenomena. The understanding of the physics behind of main mechanisms makes the reduced modeling an easier task. For the design of new machines both reduced models and CFD may be used to achieve a design. For achieving fast design resutls, reduced models are of higher interest. Indeed testing your final design is very exciting as well and proves the real applicability of the machine as well as the developed design process.
