Default slip velocity in microchannbel
Sander Nagoo
Posts: n/a
Dear all:

I would like to simulate compressible microchannel flow. The proposed model assume the fluid is a continuum but employs a slip velocity on the channel wall. I have a simple following question, If I want to calculate the slip velocity,what kind of Re I should use Re=rho*u*H/mu or Re=rho*u*2*H/mu

H -- channel high

Please give me some suggestion. Thank you.

Sander best regard
