平台推进剂催化燃烧模型

Catalyzed conbustion model for plateau propellants

为了研究平台推进剂燃烧机理 ,考虑到泡沫区内固相、气相及液相之间的各种作用 ,建立了多相反应燃烧模型 ,设计了数值解法 ,计算了相分布、燃速压力曲线等参数。初步结果表明 ,该模型可以解释平台效应 ,对推进剂配方研制有一定指导意义。

To study the catalyzed combustion mechanism of plateau propellants,a multi phase conbustion model was put forward,in which the interactions among solid phase,liquid phase and gas phase were considered.Using the numerical calculation method the phase distribution,burning rate and other parameters were calculated.From the results the plateau burning phenomena can be explained.
