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…
