Hi everyone, I am using bubbleFoam to misluate a bubble column, I want to use the tutorial example but simulate the turbulent flow, anyone can give me some hints on doing that? Thanks.

In OpenFOAM all you have to do is adjust your transportProperties file in constant/transportProperties. For example:

/*--------------------------------*- C++ -*----------------------------------*\
| ========= | |
| \\ / F ield | OpenFOAM: The Open Source CFD Toolbox |
| \\ / O peration | Version: 1.6 |
| \\ / A nd | Web: www.OpenFOAM.org |
| \\/ M anipulation | |
\*---------------------------------------------------------------------------*/
FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "constant";
object RASProperties;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
RASModel kOmegaSST;
turbulence on;
printCoeffs on;

// ************************************************** *********************** //

Then add the boundary conditions for the appropriate turbulence variables in the 0 directory (k,omega, and nu). Look in the tutorials cases for examples. i.e. the cavitatingFoam throttle example includes turbulence modelling as do many of the other tutorial cases.
