hi
i have a problem that how can i set up flow over an airship with buoyant force?
which kind of turbulent model is good for this problem?
should i apply pressure on farfield boundary condition as a function of height( z direction)?( P=P0+rho*g*(z-z0))
if i scale down my model the solution is correct or not?
should i enable enrgy equation in navier-stoks for this problem?
velocity flow over the airship is aproximately 100 km/hr.
