Contribution to the gas flow and heat transfer modelling in microchannels
This study is focused on the mathematical modelling of gas flow and heat transfer in a microchannel with the rectangular cross-section. The gas flow - the velocity slip and the temperature jump at microchannel walls. The analytical ...

Analytical solution of gaseous flow in a rectangular microchannel with second-order slip flow boundary conditions
This paper deals with the analytical solution of gaseous slip flow in a rectangular microchannel. The flow is supposed to be steady, laminar, incompressible and hydrodynamically fully developed. The velocity slip at microchannel wal...

Investigation on thermal performance of nanofluids in a microchannel with fan-shaped cavities and oval pin fins
is designed for the rectangular microchannel heat sink with an aspect ratio of 2. Four thermal resistance are used to reflect the microchannel performance. In the Reynolds number range of 132–531, the microchannel shows th...

Modeling of diffusion of injected electron spins in spin-orbit coupled microchannels
We report on a theoretical study of spin dynamics of an ensemble of spin-polarized electrons injected in a diffusive microchannel with linear Rashba and Dresselhaus spin-orbit coupling. We explore the dependence of the spin-precession and sp...
