吸热型碳氢燃料模型化合物裂解性能研究

高超声速飞行使飞行器表面热负荷急剧增加,要求燃料作为推进剂供给飞行器动力的同时满足冷却要求.不同燃料的物理热沉相差无几,利用吸热型碳氢燃料的裂解反应获得热沉势在必行.在这种条件下,单纯的热裂解已不能满足要求,引发及催化裂解作为提高燃料裂解性能的途径成为研究热点.本实验分别以正十二烷、异辛烷和甲基环己烷作为模型化合物,对...

Study on Cracking of Endothermic Hydrocarbon Fuel Compounds

As flight speed increases to hypersonic regime,aerodynamic heating becomes increasingly severe,which requires using fuel not only as an energy source but also a primary coolant.In a practical view of obtaining more endothermic heat and improving the cooling capability,endothermic reactions of hydrocarbon fuel such as cracking were essential since the sensible heat sink capacities changed slightly for different hydrocarbon fuels.In this case,thermal cracking of the fuel is not enough,and cracking with initia...
