摘要

Numerical simulation investigation about hydrophobic channels with different slip velocity was carried out based on wall slip theory in laminar flow. A method of slip boundary simulation about hydrophobic channel was put forward based on wall shear stress formula. Results are as follows: non-dimensional pressure drop ratio increases with slip velocity while flow mass is constant; there is corresponding relation between slip length and non-dimensional pressure drop ratio; non-dimensional pressure drop ratio varies from 1.41% to 16.62% when slip length varies from 4.82 μm to 66.54 μm, which is accord with the result from theory deduction. The result indicates the method about wall slip simulation is reliable based on wall shear stress formula.
