Abstract:
This paper analyses the air curtains capability to be used to prevent the smoke flow from the fire
compartments. Full size experiments have been developed and several relevant conditions to
assess smoke-tightness have been tested. During the tests the air curtain’s diffuser was
positioned horizontally in the top of a permanent opening (doors). With this configuration we
have an approximately vertical descend jet through the used opening. This paper includes the
final results of these tests. 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
compartment’s smoke exhaust.
