Turbomachinery & Propulsion

The turbomachinery and propulsion research super group studies coupled fluid mechanics, heat transfer, and thermodynamics problems with the goal of developing sustainable propulsion and power generation systems. These systems feature external and internal aerodynamic flows, two-phase heat transfer, combustion instability, and propellants and energetics, to name a few examples. Specific research thrusts include: 

• Increasing efficiency while reducing the size of gas turbine engines important to novel and new turbine architectures including hybrid electric propulsion systems 
• Leveraging advanced manufacturing techniques, including metal additive manufacturing, to create new and efficient cooling methods 
• Developing novel diagnostics (using high-speed lasers and cameras and minimally-invasive probes) as well as signal processing strategies (using statistical, machine learning, and physics-informed techniques) to study complex fluid and energy systems like swirl-stabilized combustors, supersonic jets, high-speed inlets, and more
