Saima is an unknown quantity at this point
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.

raheelrasool is on a distinguished road
You can take them as wall and specify zero as shear value to avoid boundary layer generation there and cross flow across the wall.
Just an idea!!!
