Numerical simulation of flow and heat transfer performance in branch and combined-branch microchannel [PDF]
Journal of Hebei University of Science and Technology, 2023 The pressure drop at the inlet and outlet of rectangular microchannel is large, and the temperature distribution is uneven; Fractal microchannel is limited by fractal dimension and the number of branches, so its application scope is narrow.

Tornadoes in a microchannel [PDF]
Physics of Fluids, 2009 In non-dilute colloidal suspensions, gradients in particle volume fraction result in gradients in electrical conductivity and permittivity. An externally applied electric field couples with gradients in electrical conductivity and permittivity and, under some conditions, can result in electric body forces that drive the flow unstable forming vortices ...

Overlimiting Current in a Microchannel [PDF]
Physical Review Letters, 2011 We revisit the classical problem of diffusion-limited ion transport to a membrane (or electrode) by considering the effects of charged side walls. Using simple mathematical models and numerical simulations, we identify three basic mechanisms for over-limiting current in a microchannel: (i) {\it surface conduction} carried by excess counterions, which ...
