Support for VOF solver in CFDEM

Submitted by abhishek_basak on Mon, 08/22/2011 - 20:29

Hello,

I have to solve a problem of a liquid filling into an enclosed space have loose objects (balls). To model this, it needs coupling of CFD (with VOF) and DEM. VOF is supported by openfoam, and I wonder if CFDEm simulations are possible using the VOF solver of openfoam?

Hi Abhishek,

you can combine a VOF solver with OpenFOAM. I've done first tests on that (see CFDEM Features and CFD Application Examples).

The tricky thing is to get mass balance right.

Cheers,
Chris

Hi Chris,

Thanks for the reply!...Is these a document (paper/publication) which mentions about the internal workings of CFDEM?, in particular, I want to know how the interface between the DEM and CFD modules handled. Is it sequential, and fully explicit?

I know this is a stupid suggestion, but maybe it would be helpful if a binary version of the code was placed somewhere :-)

Um..Please refer to my previous post ... I was refering to the "resolved" method for CFD and DEM coupling, i.e. using mesh sizes much smaller than that of the spheres

Hi!

>> how the interface between the DEM and CFD modules handled. Is it sequential, and fully explicit?
I'm sorry did not get the point of your question...

>> binary version of the code was placed somewhere
binary code and GPL do not match too good...
