The gathering of substantial temperature gases inside a compartment is usually a source of heat flux that can result in destruction. A ceiling jet is formed from the intersection in the plume With all the ceiling, which can result in better heat to be transferred first towards the ceiling surface area and later for the intersecting wall surfaces. The temperature on the plume is going to be biggest close to the plume centerline and for that reason the best warmth flux to your ceiling area will be at this area at this time through the duration in more info the fire.
