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. |
Re: Turbulence Model Study
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. |
Re: Turbulence Model Study
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.
