Abstract:International audienceFire induced airflow in a compartment is numerically investigated. The fire is modeled by a volumetric heat source centrally located in the fire room. Natural ventilation is provided by a door that plays the role of fresh air entrance and hot gas exhaust. Numerical simulations are carried out using the standard k-e turbulence model coupled with a near wall boundary approach namely the ``enhanced wall treatment''. The first part of this study discusses the validity of the Boussinesq approx… Show more
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.
