Evaluation of corridor smoke exhaust systems with FDS software

Abstract

A corridor smoke exhaust system is used in high buildings to exhaust smoke in case of fire. This system consists of exhaust fans, piping and dampers set in the corridors of the floors in the building. The system can be controlled automatically or manually. The evaluation of the performance of this system is a very difficult job. This paper introduces the application of FDS software to simulate fire situations in the building and the operation of the exhaust corridor smoke system. Thereby the author assesses the performance of the system in different situations and proposes measures to control the system most effectively.
