Experimental Study on Effect of Ceiling on Upward Flame Spread over Poly(Methyl Methacrylate) Sheets

Abstract:

A series of experiments was designed to investigate the effects of ceiling on upward flame spread. The result reveals that the ceiling accelerates the burning rate of upward flame under certain situations. And the acceleration is slightly increase with the increasing sample length, but almost keeps the same with different sample width. The heat release rate per unit area nearly keeps the same for the series work with ceiling or the series work without ceiling. But the heat release rate per unit area between the two series is obvious, the heat release rate per unit area with ceiling is much higher than the ones without ceiling.
