Flow Control

Active and passive manipulation of high-speed flow structures.

Methods

Active control using quasi-direct-current plasma arrays, wall injection, wall suction, and distributed or discrete actuation.
Passive control using angled wall slots, bleed, and plenum coupling to alter boundary-layer mass and momentum transport.
Systematic variation of backpressure, slot pressure, inflow distortion, and actuator state to identify control mechanisms and operating limits.
Synchronized schlieren, high-frame-rate plasma imaging, electrical measurements, distributed pressure measurements, and high-speed pressure acquisition.
Evaluation through shock position, pressure-gradient redistribution, unsteady loading, mass removal, and inferred total-pressure performance.
