Propagation de fumées

The aim of the project is to see whether it makes a difference in term of propagation of smoke to compartments outside the fire compartment, whether "normal" fire resistant doors are provided or whether doors with particular properties related to smoke propagation (Sa or Sm) are provided. Two types of building have been considered: one of horizontal shape (representative of a hotel or a hospital floor) and one of vertical shape (representative of a dxellings building). Different scenario have been considered with respect to the type of doors, the fact that different doors or windons are open or not, the presence of wind... Observed results in different compartment are the thickness of the smoke free layer, the temperature of the smoke layer, the obscurtion or the CO content.
