Low-Pressure Boundary Slip
Hi, have anybody used low-pressure boundary slip condition in Fluent?
In the forum's archive there is a plenty of questions about using velocity slip boundary condition as opposed to no-slip bc. Most of them are left unanswered...
In Fluent 6.2 there seems to be a built-in option for slip boundary condition but I haven't been able to turn it on so far. In Define/Models/Viscous there is an option "Low-Pressure Boundary Slip" that can be enabled. If the option is enabled than two additional fluid properties can be specified in Define/Materials/ . These additional properties are Thermal Accommodation Coefficient and Momentum Accommodation Coefficient.
The problem is that I can't find a way to turn in the slip in boundary conditions. The menu for specifying wall boundary condition still has only "No-slip", "Specified Shear" or "Marangoni Stress" options neither one of them seems relevant for wall slip.
I searched Fluent 6.2 manual with no success yet. The Maxwell slip model is explained in section 14.2.2. on the theoretical level without any explanation /screenshots on how to use that option.
Any advice/shared experience is greatly appreciated!!
