LES + VOF + Particle tracking
 

Hello All,

I want to perform particle tracking in a 2 phase flow (VOF model) using LES. As per my knowledge, interFoam should be able to include LES and VOF. But is there any solver which does particle tracking along with VOF+ LES.

Any help/suggestions will highly be appreciated. :)

Many thanks,
Kush

The solver compressibleInterFoam uses VOF with an LES model.

Thanks for your input.:)

And what about particle tracking on top of that?

It should be quite easy to add particles to your solver assuming that the particles stay strictly in one phase as there is no model for interaction with phase surface. To add particles to your solver, you need to add lagrangian library links to your Make/option file and add few lines to your solver. as an inspiration, you may have a look at:$FOAM/tutorial/lagrangian/rhoPisoTwinParcelFoam/ where you will find solver.

If you need something more complicated, have a look at paper and presentation of A. Dietz, T. Indiger (FluiDyna GmbH) at http://web.student.chalmers.se/groups/ofw5/Program.htm from a 5th OF workshop.

good luck

Hello , I need to implement particle tracking in compressible flows . I have incorporated intermediate mode in rhocentralfoam .
However I now wish to implement a new drag model depending on Gas pressure and temperatre . The ' basicKinematicCloud ' takes ( rho , U , g , mu) from the gas phase as inputs ( enough for SPhere drag expression) . Could you tell me how to import , P , T variables to be used in my drag model ?

parameters in injection models
 

Dear Matej,

Thank you very much for your suggestion. I was successful in validating two phase flow field established by interFoam solver for my case. I also looked in to the solver you suggested and my new interFoam solver (with particle tracking included) compiled without any error.

I searched a lot on this forum and OF site but could not understand details of injection model details.

1) what does 'parcelBasisType' means (options number/mass) ?

2) why do we need to specify 'massTotal' and 'volumeFlow' rate while we already specify 'parcelPerSecond'?

I will highly appreciate your help in developing my understanding of injection model. I tried looking at code as well but it did not help me.

Thanks,
Kushagra
