Eulerian granular flow using PBM
Dear friends,
I am using Population Balance Model coupled with FLUENT mixture model to simulate the dispersion of solid particles in the wake of moving cars. The simulated volume fraction of the secondary phase looks reasonable, which extends backwards to a certain distance behind the car. But when I plot the Population Balance variables (such as Bin Fraction and Number Density), they don't go far behind the car. It seems the model has no problem in modeling the dispersion of particles as secondary phase, but when it comes to each bin of particles, the model does not give the dispersion right.
Can anyone help?
Thanks
