This case models a three-dimensional cleansing station. It consists
of several rooms with the directional flow of air from an end to the another.
Air enters each cleansing room near the floor and leaves near the ceiling.
The source of pollution is modelled with several pipe-like exhausts of
different flow rate and pollutant concentration.
Temperature is not solved. Turbulence is modelled by means of the k-e model.
Geometry (1): Top view showing the vent, outlet, and pollutant exhausts.
Geometry
(2): Air communication between the rooms.
