Natural convection BC

April 4, 2006, 11:56

I want to model a simple natural convection on a vertical 2D plane which is hotter than ambient.

What kind of boundary condition should I use for 4 boundaries of the domain (up, down, left and right boundary of the domain)?

Boussinesq model is used.

Left boundary = Wall at specified constant temperature.

Thanks in advance

Are you trying to model the heated wall in an infinite medium? If so, use pressure boundaries for the other three boundaries.
