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…
Benchmarking Long Roll-outs of Auto-regressive Neural Operators for the Compressible Navier-Stokes Equations with Conserved Quantity Correction
Sean Current, Chandan Kumar, Datta Gaitonde +1
Deep learning has been proposed as an efficient alternative for the numerical approximation of PDE solutions, offering fast, iterative simulation of PDEs through the approximation…
Elucidating Three-Dimensional Coherent Structures in a Multi-Stream Jet
Mitesh Thakor, Datta V Gaitonde, Yiyang Sun
Nominal two-dimensional (2D) shear layers have been studied extensively, and their principal dynamics are well understood. In practical configurations, however, the behavior of suc…
Optimal and suboptimal spatiotemporal dynamics of multi-shear-layers in rectangular jet
Mitesh Thakor, Datta V. Gaitonde, Yiyang Sun
We analyze the perturbation dynamics of a complex supersonic multi-stream rectangular jet. The dynamics are examined through application of spectral proper orthogonal decomposition…
High-speed micro-actuation in a supersonic dual-stream jet flow
Melissa Yeung, Datta V. Gaitonde, Yiyang Sun
Supersonic shear layers experience instabilities that generate significant adverse effects; in complex configurations, these instabilities have global impacts as they foster compou…
Responses to Disturbance of Supersonic Shear Layer: Input-Output Analysis
Mitesh Thakor, Yiyang Sun, Datta V. Gaitonde
We investigate the perturbation dynamics in a supersonic shear layer using a combination of large-eddy simulations (LES) and linear-operator-based input-output analysis. The flow c…
