Abstract
To show the applicability of different methods of simulating fire dynamics, this paper presents a computational and experimental study of fire growth and smoke movement in large spaces. The numerical results are obtained using three methods: 1) simple correlations; 2) a two-zone model (FIre Evaluation and Risk Assessment system. FIERAsystem); and 3) a Computational Fluid Dynamics model (FDS). This paper investigates the merits of the two fire models in an effort to develop robust engineering tools to study and evaluate fire safety and smoke exhaust systems. The investigation is conducted using two case studies. The first case study simulates an enclosed pool fire located in the paint workshop of an aircraft hangar. The second example investigates the effects of a fire in a mechanically exhausted atrium space. Predictions of the numerical models of the second case study are compared with the data from a series of experiments conducted at the National Research Council of Canada (NRC) as part of a study to investigate the effectiveness of smoke management systems in large spaces.
