Compressibility Driven Wake Transition and Hysteresis over Cargo Aircraft Aftbodies
Chitrarth Prasad, Rajesh Ranjan, Daniel J. Garmann +1
Aft sections of military cargo aircraft employ flat surfaces at high upsweep angles to accommodate ramp doors, producing flow features that affect cargo-drop accuracy, paratrooper…

Intermittent Vortex Merging and Extreme Drag in Transitional Airfoil Flow
Shishir Gautam, Chitrarth Prasad
Intermittent departures from nominal Kelvin--Helmholtz shedding can produce rare and pronounced drag excursions in transitional airfoil flow. We examine these events using two-dime…

Resolvent Analysis of an Under-expanded Planar Supersonic Impinging Jet
Qiong Liu, Chitrarth Prasad, Datta V. Gaitonde
This investigation aims to assess the effect of different types of actuator forcing on the feedback loop of an under-expanded Mach 1.27 planar impinging jet using a resolvent frame…
