DispersionModel in sprayFoam

tjucus · October 27, 2014, 03:01

Hi, everyone

I am a new foamer using OpenFoam to simulate diesel spray recently; from some paper of diesel spray submodels, I got to know turbulence dispersion is of great importance to spray development. However, why the dispersionModel is turnd off in the sprayFoam solver? And when I tried to make it like this:
diespersionModel stochasticDispersionRAS
Then an error appears, stochastciDispersionRAS is not a valid model?but in some other lagrangian solvers, this dispersionModel works well.
could you help me about this problem,how can I use the stochasticDispersionRAS submodel?

Thanks a lot!

I had this same issue a few weeks ago too. This is a bug that has not yet been fixed. Search the forum for how to correct this yourself & recompile, or switch to one of the alternate solvers which implement the new dispersion structure.

See but report here:

thanks a lot for you kind help!really sorry for the quite late reply! I have solved this problem, it is just because the wrong installation. as suggested by one of my friends, I reinstalled OpenFoam-2.3.x,then it works! so I think you can also try it!
good luck!
