I am studying turbulence with the aid of CFD by solidworks, actually I have a confusion about the inlet , outlet,ideal wall and real wall conditions. I dont know what is best for me..
I set one side of the swimming tank as inlet velocity, the opposite outlet side as static pressure ,
for the other sides of the tank as ideal wall, and the robot inside the tank as real wall.
I dont know if I am write or wrong.
please correct me.
Inlet is generally where the fluid enters your domain/system. Outlet is where the fluid exits from the system/domain.
An ideal wall is one without wall shear/frictional effects. A real wall is one with wall shear/frictional effects.
Yes you are doing it right.
Just in case, you should know that you must set the walls of your tank as real wall if the extent of your tank is limited relative to the robot in real life, and you wish to set the conditions and capture the physics as closer to the real testing tank. Otherwise, if your tank is quite large such that the robot and the wall doesn't have any significant effect on each other's flow characteristics then the wall should be taken as ideal.
Your robot is going to stay as real wall because obviously friction drag is going to be their and needs to be considered under turbulent conditions.
Dear CANARDS
Thank you very much for your time, It is highly appreciated..
I am so thankful for your reply.

CANARDS explained perfectly but finally if your surface is polished, you can consider as ideal wall.
