A Computational Study on Structural Barrier to Vertical Spread of Window Spill Plume along Building Exterior Façade under External Wind
External wind is one of the major factors that influence the spread of fire along building exterior facade in high-rise buildings. Fire simulation experiments are conducted .First, under two circumstances of low-speed and high-speed side-blown wind, observing barrier of window spill plume along building exterior facade under different dimensions of windows, windowsill walls and balconies. Then the correlation between smoke temperature near the exterior facade and dimensions of window, windowsill wall and balcony is obtained by numerical fitting and dimensional analyses. The correlation indicates that, on low-speed side-blown wind, spill plume spreading diagonal up downwind, balcony width plays a leading barrier; on high-speed side-blown wind, spill plume horizontal spreading downwind, balcony extension plays a leading barrier.
