This paper describes the application of a fire field model based on the PHOENCIS CFD software to the simulation of fire induced flows in domestic-sized rooms. Several scenarios are examined consisting of various fire sizes, fire locations, and door sizes. Comparisons are based on upperlayer room temperatures, mass fluxes in and out of the fire compartment, and door-way vertical and horizontal temperature and velocity profiles. For most cases, the model agrees reasonably well with the observed trends. However, significant smearing is observed in predicted temperature profiles in the vicinity of the confining walls. A close examination of the horizontal doorway velocity profiles highlights the need for careful modelling and experimental practices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
