Large eddy simulation of smoke spread in a multi-storied building

Abstract

A fire dynamics simulator (FDS) code, based on large eddy simulation (LES) technique, has been used for simulation studies of smoke spread due to fire in a multi-storied building. The existing natural ventilation system is found to be inefficient in smoke extraction. To safeguard the stairs from smoke accumulation, various methodologies of mechanical ventilation have been adopted to analyze the situation. Suggestions on improving the safety of the building have been provided and their feasibilities have been discussed.
