对两种形状、三种厚度和不同尺寸的聚甲基丙烯酸甲酯（PMMA）板进行了一系列燃烧实验，研究了等效直径对垂直PMMA在自然对流环境中燃烧特性的影响。使用两台数码摄像机记录燃烧过程。通过电子天平记录质量的时间变化。然后从理论上分析了当量直径对质量损失率和火焰高度的影响。在理论分析中对对流和辐射传热进行了计算和建模，并与实验进行了比较。结果表明，各当量直径质量损失率的理论预测与实验测量结果吻合较好。此外，采用无量纲分析方法分析了火焰高度与放热速率之间的关系。研究发现，PMMA在自然对流环境下垂直燃烧的火焰高度主要受放热速率和当量直径的影响。
A series of combustion experiments of polymethyl methacrylate (PMMA) plates with two shapes, three thicknesses, and different sizes was performed to investigate the effects of equivalent diameter on combustion characteristics of vertical PMMA in a natural convection environment. Two digital video cameras were used to record the burning process. The temporal variation of mass was recorded by an electronic balance. The influence of equivalent diameter on mass loss rate and flame height was then analyzed theoretically. Convection and radiation heat transfer were calculated and modeled in the theoretical analysis and compared to experiment. The result shows that the theoretical prediction of mass loss rate for each equivalent diameter is in good agreement with the experimental measurements. In addition, the relationship between flame height and heat release rate was analyzed using dimensionless analysis method. It was found that the flame height for vertical PMMA burning in a nature convection environment is dominated by heat release rate and equivalent diameter.
