vof help
 
can i use a vof model for simulating turbulent flow.while im using im getting an error.can anyone help me in this regard.

there is no turbulence modelling available in vof. u can't apply is ur problem is twophase flow?????

i have to simulate the flow for a body floating in water

Hi

Turbulence modelling is available in vof, but its not suitable for multiphase problems. e.g I had simulated flow around a ship using VOF, k-epsilon model and I found that resistance was over predicted. It was more then twice the experimental value.

Laminar model agreed better with the experimental results.

Hi Satyanarayana

Try VOF (geometrical reconstruction), laminar, unsteady ( for both steady and unsteady state problems)..

What error are you getting? You might be getting it because of wrong inputs.

Regards, Manoj

Re: vof help
 
im getting the turbulence intensity is limited to 1*10^5 in sme cells for some iterations and then it is showing floating point error and then stopping,can u help me in this regard
