Space-time proper orthogonal decomposition of actuation transients: plasma-controlled jet flow
Brandon Yeung, Oliver T. Schmidt
We investigate the forcing-induced transient between statistically stationary and cyclostationary states. The transient dynamics of a turbulent supersonic twin-rectangular jet flow…

Spectral dynamics of natural and forced supersonic twin-rectangular jet flow
Brandon Yeung, Oliver T. Schmidt
We study the stationary, intermittent, and nonlinear dynamics of natural and forced supersonic twin-rectangular turbulent jets using spectral modal decomposition. We decompose larg…

Revealing Structure and Symmetry of Nonlinearity in Natural and Engineering Flows
Brandon Yeung, Tianyi Chu, Oliver T. Schmidt
Energy transfer across scales is fundamental in fluid dynamics, linking large-scale flow motions to small-scale turbulent structures in engineering and natural environments. Triadi…
