A Computational Study on Effect of Balcony on Vertical Spread of Window Spill Plume Along Building Exterior Facade

The barrier effect of balcony is significant on vertical spread of window spill plume along building exterior facade. A series of reduced- scale fire simulation experiments were carried out in order to investigate the reduction of vertical fire spread due to the present of a balcony in different depth and width. Finally conclude:(1)the depth and width of balcony play different degrees of barrier effect on vertical spread of window spill plume along building exterior facade, (2)When the balcony width is longer enough, the balcony depth playing dominant barrier effect, (3)when the balcony depth is long enough, with th% balcon9 width increase, the wall temperature decrease slightly.These conclusions provide fire prevention of the building exterior faca$e with a reference.
