Maximum temperature rise of fire plume ejected out of the compartment window with a horizontal eave
This study focuses on the maximum temperature rise of fire plume ejected out of the compartment window with a horizontal eave. Based on the symmetry of ejected plume and pictures recorded by the cameras in the study, the shape of ejected thermal plume out of the window under the eave is suggest as an isosceles trapezoid, and the ejected thermal plume rising at the edge of the eave is assumed to be a rectangular fire source. The dimensions of the rectangular fire source are theoretically deduced for compartment fire process of different window geometry, width of eave, and heat release rate, according to the conservation of plume mass. The previous predictive model for plume temperature proposed by Quintiere is popularized to the ejected flame above an eave by including the dimensions of the rectangular fire source as well as the width of eave. The results would provide theoretical guidance to the application of fireproof eave in high‐rise building for fire protection designs.
