What's the influencing factor of slipping coefficient?

jimzhou · February 10, 2011, 04:52

In CFD specially if fluid has complex rheology, the slipping coefficient existed between fluid and wall can affect the flow greatly, i want to know except for it depending on the wall coarseness, wall material ect. and what other factors could change it such as viscosity of fluid?

Thanks for your offering in advance.
