Side Wind Effect on the Flow Behavior of the Window Plume
Wind action on the flow behavior of the window plume along the exterior wall of a building was studied by analytical and numerical methods. Heat release rate of fire and outside wind speed were varied in the study. It was found that the window plume would flow downward under side wind. Fire might spread to the room above the window when the wind speed was low. With the wind speed increasing, the plume would be blown to downward direction, giving hazardous conditions to rooms at downstream of the wind. The tilted angle of the window plume was derived by theoretical analysis.
