Flow instability in Stokes layer of Carreau fluids
Mengqi Zhang, Dongdong Wan, Huanshu Tan
This study investigates the influence of shear-thinning on the instability of a prototype time-periodic flow, the Stokes layer, in Carreau fluids. The time-dependent base flow was…
On the intracyclic instability in Stokes layers
Mengqi Zhang
Time-dependent fluid dynamics plays a crucial role in both natural phenomena and industrial applications. Understanding the flow instabilities and transitions within these dynamica…
A Diffuse-Interface Marangoni Instability
Xiangwei Li, Dongdong Wan, Haohao Hao +3
We investigate a novel Marangoni-induced instability that arises exclusively in diffuse fluid interfaces, absent in classical sharp-interface models. Using a validated phase-field…
Reinforcement-learning-assisted control of four-roll mills: geometric symmetry and inertial effect
Xuan Dai, Da Xu, Mengqi Zhang +1
Embedding the intrinsic symmetry of a flow system in training its machine learning algorithms has become a significant trend in the recent surge of their application in fluid mecha…
Reinforcement-learning-based control of turbulent channel flows at high Reynolds numbers
Zisong Zhou, Mengqi Zhang, Xiaojue Zhu
Deep reinforcement learning (DRL) is employed to develop control strategies for drag reduction in direct numerical simulations (DNS) of turbulent channel flows at high Reynolds num…
Linear instability in thermally-stratified quasi-Keplerian flows
Dongdong Wan, Rikhi Bose, Mengqi Zhang +1
Quasi-Keplerian flow, a special regime of Taylor-Couette co-rotating flow, is of great astrophysical interest for studying angular momentum transport in accretion disks. The well-k…
