How to set wind tuunel Boundary Condtions?
Hi ,
I have a problem in which a heater is on leading edge of an airfoil, placed in wind tunnel. Air is inside the tunnel at -5C. And water spray by using atomizer is also there. This airfoil is placed inside the wind tunnel.I want to setup the boundary conditions. I took, 1. Velocity inlet (bcoz i know the initial velocity which is constant in entire process) 2. Outflow 3. The bottom and top wall (wall with zero shear) I want to know what could be the boundary conditions for top and bottom walls of Wind tunnel?:confused: It is very urgent. Many Many thanks in advance.

1. 2D or 3D ?
2. what's your Turbulence model ? 3. Slip wall or symmetry plane is first and second choice I think. |
It is 2D. I m using (VOF+Solidification) , k-eps (2-eq) model.
I didn't took symmetry bcoz heater is not symmetric. I draw whole airfoil. I have not use fluent b4 and it is my 6-credit project. Please help me. Saima |
