NUMERICAL STUDY OF SMOKE MOVEMENT AND BEHAVIOUR AT AUDITORIUM HALL

Abstract

Summary: This research shows the approach for the smoke layer interface at particular distance above the highest walking surface in an auditorium, The associated smoke exhaust capacity required to provide a large clear height is substantial. Further concerns about the make-up air requirements, especially given that the maximum velocity of 6.0 m/s for the make-up air in case utilizing mechanical ventilation and 4 m/s in case none forced ventilation as in this study utilizing ANSYS Fluent V.18.2 CFD software. Based on that this thesis will discuss how much smoke air should be extracted to enable people escaping from that auditorium in safe way.
