Stability of smoke layer under sprinkler water spray

2005 ASME Summer Heat Transfer Conference, HT 2005, San Francisco, CA, 17-22 July 2005Stability of smoke layer induced by a fire will be studied in this paper. A series of full-scale burning tests were carried out to study the interaction of the hot smoke layer with a sprinkler water spray. A new rig was built to give a smoke layer. The results show that the stability of a smoke layer will be disturbed by the discharged water spray. The operating pressure of the sprinkler system is a key point. When the smoke layer lost its stability, the dragging force acting on the smoke layer was found to be less than the buoyancy.Department of Building Services EngineeringRefereed conference pape
