The velocity depends on the heat transfer rate and the difference of density and temperature in your system. You need a heat transfer coefficient which is f(Re,Pr,Gr,...) and a temperature-dependent expression for the density or the Boussinesq-approximation.

There is a model in the model gallery which is very similar to my problem : free convection in a water glass
comsol.com/showroom/gallery/195/
Unfortunately, I don't find it in the Model Library. Is there another way to have access to this model ?
Thanks
Nicolas

hi, someone have or know where I can found the solution manual of book Convection Heat Transfer, third edition of author Adrian Bejan, because I need very much in my pos-graduate. thanks.
my e mail is augusto_bassan@yahoo.com.br
