文章基于数值模拟方法,对JP-10高密度燃油在某型弹用涡喷发动机燃烧室中的燃烧过程进行了研究,并与原燃油RP-3燃烧的数值模拟结果进行了对比。结果表明,在与RP-3燃烧相同的空气进口质量流量情况下,JP-10在该涡喷发动机内能正常燃烧,且供油时间比之RP-3要增加20%左右。使用JP-10,火焰筒内部高温区范围有所减少,降低了燃烧室结构的热负荷。保证燃油流量相同条件下使用JP-10,火焰筒出口处温度分布系数比采用RP-3的要小。
Based on the numerical simulation method, the combustion process of JP-10 high-density fuel in the combustion chamber of a certain type of projectile turbojet engine was studied and compared with the numerical simulation results of RP-3 combustion of crude oil. The results show that JP-10 can normally burn within the turbojet with the same air inlet mass flow rate as RP-3, and the fueling time is about 20% higher than that of RP-3. With JP-10, there is a reduction in the high temperature zone inside the flame tube, reducing the thermal load on the combustion chamber structure. JP-10 is used to ensure the same fuel flow rate, and the temperature distribution at the outlet of the flame tube is smaller than that of RP-3.
