For those interested: I added stochastic fluctuations in an incompressible LES context as well (the original dispersion model is only implemented for RANS). Just compile the library attached and add
dispersionModel stochasticDispersionLES; or dispersionModel gradientDispersionLES; to the kinematicCloudPropertries dictionary. Have a look at the 3D cavity example. Note: The same trick has been just to the intermediate.tar.bz2.gz archieve: remove gz extension and unpack it with tar xjvf (using bzip2). I also update the kinematicParticleTracks utility compiled against the new library. Also some more info per particle track is written (UTubr and tTurb for instance). One question from my side again: does anybody now how to write the particles independently from the fields ? I would like to write the particle at a higher frequency than I write the field files. Hopefully any knows how to do this. Thanks! Regards Eelco |
