Hi,

I am new to CFD and OF, i am doing simulation of a fuselage. I am confused about which turbulence model to be used..?? And at what conditions one should use them...??
Can anyone clearly explain this...

Thanks.

Are you doing the simulation of the inside of the fuselage, then buoyantPimpleFoam might be the best option. If you're doing a sim of the airflow around the plane then I suppose that would work too, you probably cannot model supersonic flow though with it, not sure about other solvers, there's sonicFoam.

Hi Andrew,

I think you confused TURBULENCE MODEL with SOLVER. I wanted to know about different turbulence models like SA, SST, k-epsilon, etc...

See if this helps

You might have better responses if you explain how you want to setup your fuselage. Is it supersonic case, etc.
