摘要 利用高度为14 mm的水平窄通道对微重力条件下聚甲基丙烯酸甲酯(PMMA)和聚乙烯(PE)塑料材料表面的火焰传播进行了地面实验模拟研究。在环境气体氧气浓度为30%和50%、低速气流速度小于15 cm/s的实验条件下,实验测量了窄通道内材料表面火焰传播速度随气流速度的变化,它们与微重力下热厚材料火焰传播速度的理论预测结果符合得相当好。分析认为,窄通道能够有效地限制浮力对流,提高燃料表面固相热辐射在火焰传播中的相对作用,从而提供模拟微重力下热厚材料表面火焰传播特性的实验环境。 The flame spread over polymethyl methacrylate(PMMA) and polyethylene(PE) fuels have been investigated in a narrow channel with height of 14 mm.Other variables include flow velocity (less than 15 cm/s) and oxygen concentration(30%and 50%).The flame spread rates are measured as a function of flow velocity.A good agreement between the experimental results and microgravity theoretical prediction is obtained.The experiments show that,because the buoyancy-driven flow is suppressed to such a degree that the role of surface radiation in solid phase is relatively enhanced,the narrow channel apparatus can provide a simulated microgravity condition.
