Inclusion of gravity in 3D natural convection problem with heat flux

Please login with a confirmed email address before reporting spam

Hi all,
I am modelling a solar water heater and in that i wish to include gravity force. The water heater model is a thermosyphon based system which works on the movement of hot water upwards due to reduction of its density.
So, how do i include volume force and what are the different boundary conditions or initial values that I need to specify.
Also, when i ran the simulation just by specifying volume force, the results came out to be faulty.
Assistance needed. Thanks a lot.
