Hi all,

I am running a turbulent 2-D natural convection problem with a differentially heated cavity. The velocity plots I am generating are only reaching about 0.002 m/s when the experiment I am modeling gives velocities at about 0.006 m/s.

Does anyone have any ideas on how to change my model? I've tried changing the turbulence parameters of c_mu, c1_epsilon, c2_epsilon, etc. and none of them make that much of a difference (only about 10% difference in max velocity.)

I would appreciate any suggestions that any of you may have.

Thanks,

Ryan
