PhD project:

Title:    Unsteady numerical simulation of the interaction between pressure-gain combustors and high-pressure turbine stages

Short description: The PhD student will be asked to investigate the topic of the interaction between the combustion chamber and the high-pressure turbine for thermodynamic cycles based on pressure-gain combustors. In detail, the PhD student will have to design a component to mitigate fluctuations in the exhaust of a deflagration-type combustor to allow adequate operation of the high-pressure turbine; he will have to design a high-pressure subsonic gas turbine stage to be coupled to a rotating detonation combustor; he will have to study the interaction between a rotating detonation combustor and a row of vanes and then design a cooling system that mitigates the effects of high temperature. All activities will require the use of state-of-the-art numerical methodologies. The first two activities will give rise to experimental campaigns carried out by the project partners.

Supervisor: Dr. Simone Salvadori

Gallis Panagiotis holds a MEng in Mechanical Engineering and specializes in Fluid Dynamics. During his academic studies at the department of Energy of the Aristotle University of Thessaloniki, he developed expertise in the area of Aeronautics and Powertrains. His thesis was concerned with the experimental visualization of compressible flow phenomena in an ORC supersonic turbine rotor, utilizing a water table. Following his undergraduate studies, he completed a research master program, offered by the Von Karman Institute in Belgium. Within the context of the aforementioned course of study, he conducted a research project focusing on the stall inception investigation of the LEMCOTEC H25 test section. Among the scientific fields he explored throughout this research program were Experimental Fluid Dynamics, Signal Processing Methods, Turbomachinery Design and advanced Axial Compressor's Aerodynamics.

His research interests revolve around CFD analysis, Turbomachinery Optimization and Secondary Flow structures.
