Reinforcement-learning-based control of convectively-unstable flows
Da Xu, Mengqi Zhang
This work reports the application of a model-free deep-reinforcement-learning-based (DRL) flow control strategy to suppress perturbations evolving in the 1-D linearised Kuramoto-Si…
Moffatt eddies in electrohydrodynamic flows: numerical simulations and analyses
Xuerao He, Zhihao Sun, Mengqi Zhang
We study numerically a sequence of eddies in two-dimensional electrohydrodynamic (EHD) flows of a dielectric liquid, driven by an electric potential difference between a hyperbolic…
On the large-Weissenberg-number scaling laws in viscoelastic pipe flows
Dongdong Wan, Ming Dong, Mengqi Zhang
This work explains a scaling law of the first Landau coefficient of the derived Ginzburg-Landau equation (GLE) in the weakly nonlinear analysis of axisymmetric viscoelastic pipe fl…
Numerical Study of Viscoelastic Upstream Instability
Sai Peng, Tingting Tang, Jianhui Li +2
In this work, we report numerical results on the flow instability and bifurcation of a viscoelastic fluid in the upstream region of a confined cylinder in a narrow channel. Two-dim…
Nonlinear spatiotemporal instabilities in two-dimensional electroconvective flows
Zhe Feng, Dongdong Wan, Bo-Fu Wang +1
This work studies the effects of a through-flow on two-dimensional electrohydrodynamic (EHD) flows of a dielectric liquid confined between two plane plates, as a model problem to f…
