How to set the wind tunnel Boundary conditions in Fluent???
 
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.
Regards,
Saima

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!!!
