Dear Experts,

I am solving a hopefully very simple problem before starting my project problem but I am not able to do it any how. The problem has a hollow vertical cuboid with top and bottom open. It's one of the vertical walls is hot and rest are insulated. I expect the fluid to rise along the hot wall but it's not happening. The physics of the problem which I set is as follows. 1) non buoyant flow, 2) inlet and outlet are opening with static pressures zero. 3)rho*g*beta*Delta T was added to momentum equation to incorporate buoyancy.

Plz suggest where I am getting wrong.

Hi Amit,

Why did you put the bounancy effects in the momentum equation (I assume as a momentum source) rather than using the buoyant flow option? I suspect your problem is there. I would just use the buoyant flow option.
