I have some barrier and I want to solve my problem axisymmetric.
I attach you my result but it's not true, I can't understand why the streamlines go up instead of going right!!!?!?!??
air enter from inlet and out side the barrier is atmosphere, actually air from indoor go to outdoor. and I rotate my model 90 degree to solve the problem axisymmetric.
what should I do to preventing the fluid going up??!?? if you rotate it -90 it should operate such as a stack.
Is here anybody that can reply my questions????!?!?!?
please help me!!!!:(
The following post would be of help:
thank you mali
but my problem was free convection and I had forgot setting my fluid an ideal gas.
I think, you could extend calculation domain
my answer can be wrong... but
In my opinion, outflow condition(neumann boundary condition) doesn't likes
backflow, so, if you have enough computer resource, how about extend it's
// my mother-language is not an English, please forgive my grammatical error
thank you Cartman,
It's done, I select my density of material a Bussinique model and it give me well solutions.
