A STUDY OF COMPARTMENT FIRE UNDER FORCED VENTILATION: EXPERIMENTAL AND COMPUTATIONAL FLUID DYNAMICS MODELING

Abstract

This paper discusses on the dynamic behavior of the flame and smoke inside a compartment fire. The compartment can be referred to a room, road tunnel, duct, compartment or a building. A series of small scales experiments were carried on four rectangular ducts that have the same height (250 mm) but different widths (125 mm, 250 mm, 500 mm and 1000 mm). Fire simulations on the same compartments were performed to investigate the effectiveness of Computational Fluid Dynamics (CFD) in predicting fire phenomenon. CFD was found capable to predict fire phenomenon such as flame shape, flame height and flame tilt angle similar to the experiment.
