Summary0000440: dispersion model with lagragian particle tracking model for incompressible flows
DescriptionAll particle tracking solvers such as sprayFoam and reactingFoam are based on compressible solvers. Often, however, particle tracking needs to be included in incompressibel flows without reactions, such as pimpleFoam. This can be done by using the kinematicCloud particle library. Similar as in icoUncoupledKinematicParcelFoam, a pressure field in Pa needs to be included, next to the pressure field required for the pimpeFoam in m2/s2 (normalized with rho). I have written this solver, however, there was one problem: all dispersionModel can not be used, as in the lagragian particle library the references to the turbulence models are explicitly compressible. Therefore, I have made a new library based on the original one in which all the references have been changed to incompressible. If this library is used, now also the dispersion models can be used in incompressible particle tracking solvers as well. For a more detailed description of my approach, please have a look at http://www.cfd-online.com/Forums/openfoam-solving/97629-dispersion-model-lagragian-particle-tracking-model-incompressible-flows.html [^]

My methods seems to work. Hopefully this incompressible particle tracking library can also be included in the next OF release.

Thanks for your thoughts. However, to simply copy an entire library in this way is not good practice, as code maintenance is severely compromised.

I've made some changes that allow the use of incompressible turbulence models under commit af4126d
