Research
Research themes in unsteady aerodynamics, flow control, diagnostics, and modeling.
The Hahn Lab studies flow physics relevant to high-speed propulsion, combustion systems, and blade aerodynamics. Experiments, computations, and reduced-order analysis are used together to identify mechanisms and develop predictive models.
Unsteady Aerodynamics
Shock system dynamics, flow separation, and shock-combustion coupling.
Flow Control
Active and passive manipulation of shock systems, boundary layers, and reacting flows.
Optical Diagnostics
Schlieren methods, mid-infrared imaging, and event-based sensors for quantitative 2D measurements.
Modeling and Computation
Physics-based and reduced-order models for prediction, interpretation, and control.
