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…
Conditional space-time POD extensions for stability and prediction analysis
Spencer Stahl, Chitrarth Prasad, Hemanth Goparaju +1
The correlation and extraction of coherent structures from a turbulent flow is a principle objective of data-driven modal decomposition techniques. The Conditional space-time Prope…
Turbulence Modeling of 3D High-speed Flows with Upstream-Informed Corrections
Chitrarth Prasad, Datta V. Gaitonde
Turbulence modeling has the potential to revolutionize high-speed vehicle design by serving as a co-equal partner to costly and challenging ground and flight testing. However, the…
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…
A Robust Physics-based Method to Filter Coherent Wavepackets from High-speed Schlieren Images
Chitrarth Prasad, Datta Gaitonde
A complete understanding of jet dynamics is greatly enabled by accurate separation of the acoustically efficient wavepackets from their higher-energy convecting turbulent counterpa…
A Time-Domain Linear Method for Jet Noise Prediction and Control Trend Analysis
Chitrarth Prasad, Datta V. Gaitonde
Large-scale turbulent structures in the form of coherent wavepackets play a significant role in the generation of prominent shallow angle noise radiation of jets. Economical predic…
