Spatial and temporal prediction of temperature distribution in a naturally and mechanically ventilated compartment

Abstract

The present study is a numerical attempt for the prediction of the variation of the flame temperature inside a compartment. The study focuses on calculating the temperature of the fumes that varies at each point vertically and radially as if various thermocouples would be places at the same point. A radiative and convective transfer modeling is considered for a 3D geometry compartment, equipped with a door, a window and subject to a localized fire, with stationary heat release rate (HRR) during a prescribed exposure time. Dealing with any fire phenomenon requires a fire simulator called Fire Dynamic Simulator (FDS) which aims to mesh the compartment then calculate the temperature at each node by performing a thermocouple role virtually. So with the new technology someone can study any phenomenon virtually without using classical methods by handling with the appropriate devices
