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?


It is very urgent.

Many Many thanks in advance.
Regards,
Saima

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.
