Air-Breathing Propulsion and Turbomachinery Aero-Heat Transfer

Modern air breathing propulsion systems benefit from novel developments in the fields of aerodynamics and heat transfer. All modes of heat transfer, analytical, computational and experimental fluid dynamics; steady and unsteady turbine and compressor aerodynamics; turbine cooling methods, novel aero-thermal component design innovations and non-intrusive research tool developments are the key supporters of this research area.

The turbomachinery areo-heat transfer laboratory at Penn State operates one of the unique large-scale turbine research rigs in the United States. A wind tunnel for convective heat transer applications, a linear cascade facility with an exit Mach number of 0.8, various ducted fan research set-ups, calibration jets, conventional aerodynamic probes, non-intrusive flow diagnostics systems and many data collection and processing systems are available in our laboratory.

The research studies benefit from an already operational infrared thermography system and liquid crystal based convective heat transfer mapping system. Our recent efforts in the high performance computing for turbomachinery aero-thermal investigations are performed in dedicated parallel computing environments.
