Abstract:
This paper analyses the possibility of use of air curtains to prevent the smoke flow to outside of
fire compartments. These air curtains are installed in an approximately vertical position through
vertical permanent slots (doors). Full size experiments have been developed and several
conditions relevant to smoke-tightness have been adopted. It was concluded that it is possible
to obtain smoke-tightness, provided that the adequate parameters of the plane jet are adjusted
in association with smoke exhaust from the compartment.
