slip boundary condition
 

hi,
I am new to ansys fluent, I am analyzing fluid flow (single phase) and heat transfer in microchannel, for that i have to use slip boundary condition, in ansys fluent we need to specify wall shear stress for this, but i dont know how to do this. does anybody have any experience for this or any tutorial for this
please help

:)

add it as wall boundary condition. Choose edit option, specify shear stress=0.

For single phase laminar flows in the slip flow regime, the "Slip Boundary Formulation for Low-Pressure Gas System" is what you need.

slip wall
 

Hi All,

I am using flow around cylinder, the shear stresses at the wall need to be specified to constant value. In this option, there are 3 components for the shear stresses, i.e. x direction components and so on.

Does anyone know for example how can set these values for cylinder surface
Regard.
