dreamz is on a distinguished road
I am solving natural convection flow in a 2D cavity whose walls are at different boundary conditions. Two walls are at high and low temperatures while other two are adiabatic. I enabled gravity, took boussinesq approximation for air, yet I am unable to get convergence. May I know, how to approach this problem..?
According to previous research, a circular flow will develop inside the cavity since flow is purely due to natural convection...
