title = "Experimental and Numerical Study on the Ignition of LOX/LCH4 Liquid-Liquid Swirl Coaxial Engine",
abstract = "To improve the stability and reliability of the ignition process of liquid rocket engines, experimental and numerical studies were conducted on the LOX/LCH4 liquid-liquid swirl coaxial engine using a torch igniter. Based on the designed timing, the experiment can achieve stable ignition. The determination of the time for liquid propellant to enter the main combustion chamber based on the experimental pressure curve is proposed. According to the determined time, a 6-step reaction mechanism simulation model was established. The established model was used to simulate the 3-D transient ignition process, and the simulation results were in good agreement with the experimental results. The simulation results show that after 15ms of LOX entering, a fire core appears at 8D0 downstream of the injector. During 45ms of LCH4 entering, the two propellants are mainly mixed and evaporated, and it takes 310ms to reach a stable combustion state (calculated from the time of LOX entering).",
