Predicting liquid properties and behavior via droplet pinch-off and machine learning
Jingtao Wang, Qiwei Chen, C Ricardo Constante-Amores +3
Here we demonstrate that the time-evolving interface observed during droplet formation, and consequently the resulting morphology nearing pinch-off, encode sufficient physical info…

Stabilizing Rayleigh-Benard convection with reinforcement learning trained on a reduced-order model
Qiwei Chen, C. Ricardo Constante-Amores
Rayleigh-Benard convection (RBC) is a canonical system for buoyancy-driven turbulence and heat transport, central to geophysical and industrial flows. Developing efficient control…

Low-dimensional multiscale dynamics of intermittent reversals in turbulent Rayleigh-Benard convection
Qiwei Chen, C. Ricardo Constante-Amores
We investigate whether a strongly turbulent flow with intermittent large-scale reorganizations admits a compact state-space description. As a representative high-dimensional chaoti…
