simpleReactingParcelFoam Secondary Breakup Model

Hey All,

I've got a quick question. I can't figure out if the following breakup models have been implemented in the simpleReactingParcelFoam solver...

Code:

$FOAM_SRC/lagrangian/spray/submodels/BreakupModel

It appears they were implemented in the sprayFoam solver, because I found these keywords in the sprayCloudProperties file in the aachenBomb tutorial...

Code:

atomizationModel none;

breakupModel    ReitzDiwakar; // ReitzKHRT;

However, I did not find those keywords in the reactingCloud1Properties file of the verticalChannel tutorial for the simpleReactingParcelFoam solver. Adding those keywords doesn't do anything either.

Has anyone used any of the secondary breakup models in simpleReactingParcelFoam? If so, can someone share with me how to enable them? I'm using the later git versions of 2.3.x (ab7c7a7).

Thanks!

Brock

Nope, the secondary breakup models are implemented in the liblagrangianSpray library, and the only solver that uses (i.e. links against) this library is sprayFoam.

Making these models available in other solvers, requires you to implement your particles as basicSprayCloud (as in sprayFoam).

You should however note that basicSprayCloud is based on ReactingCloud, whereas the simpleReactingParcelFoam solver is based on ReactingMultiphaseCloud, hence no multiphase particles with SprayCloud.

Cheers,
