Hi,
I am trying to use Fluent to solve a simple problem, the two phase flow between two parallel plates, for my course project. The physical model is described here: http://www.chemecomp.com/poiseuille_immiscible.pdf Or here: http://test.interface.free.fr/Case14.pdf I am trying to get the same result numerically. My mesh is like this: mesh.JPG 2D planar steady state problem. I am using VOF and Laminar models. Didn't change setting. I have two fluid with same density but different viscosity. I think the result should not be a function of density. I meshed the interface. I tried on "coupled wall", but the velocity is set to 0 at interface. I don't know how to make the wall is shear stress balanced. Without "coupled wall", the velocity is continuum at the interface, but fluid will cross the interface, which is not what I want. Like this (contour of void fraction): voidfraction.JPG My question is, what should I do to make an interface in the middle such that the two fluids can't cross it, but balanced with shear stress? Thank you very much. hopehope |
