Marie Curie Research Fellow
TECHNICAL UNIVERSITY BERLINOccurring shock systems in the supersonic flows, e.g. at the leading edge of the turbomachine rotor, reduce the machine efficiency drastically and threaten the responsible use of energy. The started project aims at developing a new understanding of the shock establishment and high-frequency response within the rotor. It is divided into an outgoing phase at Purdue University and a return phase at TU Berlin. During the outgoing phase, a numerical analysis of the observed phenomenon will be conducted to develop a reduced model based on 3D characteristics. This model will thoroughly be validated by advanced experimental measurements. Back at the TU Berlin, the final applicability of the reduced model and the functionality of the novel concept will be assessed by a design optimization of a turbine and a compressor geometry.

PURDUE UNIVERSITYDuring the outgoing phase of the Marie Curie Global Fellowship, the project aims at developing a new understanding of the shock establishment and high-frequency response within the rotor. A numerical analysis of the observed phenomenon will be conducted to develop a reduced model based on 3D characteristics. This model will thoroughly be validated by advanced experimental measurements. The aim is to transfer a fully validated model, which can be used for the design of transonic turbines and compressors.

POSTDOCTORAL RESEARCH ASSISTANT
Universitat Politècnica de València (UPV)One-dimensional simulations of an entire internal combustion engine and validation of integrated inhouse coded turbocharger compound considering a novel extrapolation model (developed during PhD thesis) were performed. Further, CFD simulations of turbocharger turbines at choked conditions were performed and supervised. Studies of scaled turbocharger geometries considering similitude analysis were supervised and CFD simulations were launched. Finally, turbocharger acoustics were numerically assessed at pulsating and steady flow conditions.

PURDUE UNIVERSITYDevelopment of a novel concept of supersonic radial turbines with axial inflow. The design was optimized by means of a multiobjective optimizer. The heat transfer and aerodynamic performance of the final design exposed to the outflow of a rotating detonation combustor were numerically assessed. A provisional design patent has been filed.

Graduate Student Assistant
German Aerospace Center (DLR)A Study on the meshing and simulation of semi-clearances of variable stator vanes was performed. Occurring divergence problems related to meshing strategies were successfully analyzed. Effective advice for the meshing of semi-clearances and tip clearances could be given to enhance the numerical stability of the simulations.
2013 2012AACHEN, GERMANY
RWTH Aachen UniversityThe numerical validation of a radial compressor and compressor map calculation of a mixed flow compressor was conducted. The validation of a publicly available test case, which was frequently used in the literature led to the conclusion that an important pressure loss was previously neglected. The neglect was cause of rather big differences between test case and simulation results. Further, the aerodynamics of a mixed flow compressor were analyzed and compared to common radial compressor aerodynamics.

Doctor of Philosophy (PhD)
Universitat Politècnica de València (UPV)The pulsating flow of the engine exhaust gases causes high variations of turbine inlet mass flow, total pressure, and total temperature. This pushes the turbocharger turbine operation towards extreme off-design conditions. My thesis supplies new insights into the three-dimensional flow field under these conditions as well as a novel one-dimensional extrapolation model and new loss sub-models. Additionally, an experimental procedure for this hardly measurable conditions was developed.
