Nonlinear scalings emerge in a linear regime: an observation in electrokinetic flow
Jin'an Pang, Guangyin Jing, Xiaoqiang Feng +2
In nonlinear systems, small perturbations are conventionally attributed to negligible nonlinearity, justifying linear approximations. Here, we uncover a notable exception to this p…
Influence of chemical environment on the transition of alternating current electroosmotic flow
Yu Han, Zhongyan Hu, Kaige Wang +1
Electroosmotic flow (EOF) is a ubiquitous phenomenon at the solid-liquid interface when an external electric field is applied. Despite its prevalence, the characteristics and mecha…
Transition routes of electrokinetic flow in a divergent microchannel with bending walls
Yanxia Shi, Ming Zeng, Haoxin Bai +6
Electrokinetic flow can be generated as a highly coupled phenomenon among velocity field, electric conductivity field and electric field. It can exhibit different responses to AC e…
Quad-cascade picture of electrokinetic turbulence
Yanxia Shi, Jin'an Pang, Yueqiang Zhu +10
Turbulence, ubiquitous in nature and across various systems, exhibits chaotic and intermittent fluctuations in space and time, defying precise prediction. For nearly a century, ext…
