Default Turbulence Model Study

Dear Fluent Users,

I am studying the flow in the simplified 2d radiator with 10 tubes. Before doing this I am doing a model study to see which turbulence model is suitable for this problem. Can anyone suggest a model which is suitable for this problem, and if not the steps to be followed during the model study, I mean how can we decide which model is suitable.

Thanks

Sridhar.

Are you interested in the tube-side or shell/external-side of the radiator?

Hi Lanre,

I am intrested in flow inside the radiator tubes. I made a simple radiator with inlet, inlet connected to inlet tank which is connected to 10 tubes(each 5mm width)and then to a outlet tank and to outlet. I am studying the effect of inlet and outlet position on the fluid flow across the tubes and overall pressure drop between inlet and outlet.

Thanks. Sridhar.

First determine whether the flow is indeed turbulent in the entry and discharge headers, and in the tubes. If the flow is turbulent, I would suggest the RNG k-e model with non-equilibrium wall functions for your developing boundary layer in the tubes.
