Library case Y610: Rain and snow : effect of interphase friction.

This demonstration shows how the two-phase option of PHOENICS, library case W249, is extended by PLANT to permit simulation of the relative movement of water (rain, or snow) and air.

PLANT is used to introduce patchwise discontinuity in interphase friction distribution: the particulate phase fragments in the bottom part of the domain are much less influenced by air, than the ones of the upper part. The inspection of PHOTON pictures show what happened near the ground: the gravitational sedimentation is increased and the air becomes purer.
