Thermo-hydraulic investigation of two stepped micro pin fin heat sink having variable step size [PDF]

E3S Web of Conferences, 2023
To achieve enhanced flux dissipation, microchannels heat sink are being effectively implemented in various engineering processes. Here, a numerical analysis is to be carried out on an open stepped micro pin fin heat sink (MPFHS) with different step size.

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 ...

Bionic microchannels for step lifting transpiration

International Journal of Extreme Manufacturing, 2023
Those various cross-sectional vessels in trees transfer water to as high as 100 meters, but the traditional fabrication methods limit the manufacturing of those vessels, resulting in the non-availability of those bionic microchannels.

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 ...
