  • 为了深入理解横向气膜作用下液体射流的破碎雾化特性, 设计了一种以空气和水为模拟介质的针栓喷注单元, 并通过两相流大涡模拟和背景光成像对大气环境下其近喷孔区域内的液体射流破碎过程和动态特性进行研究. 通过大涡模拟液体射流的表面波主导破碎过程得到了针栓喷注单元近喷孔区域的喷雾场建立过程, 亚声速气流离开狭缝后膨胀加速为超声速气流, 经过液体射流上游的脱体弓形激波后减速增压. 而在液体射流上下游之间的压差作用下, 射流往下游发生弯曲的同时迎风面出现Rayleigh-Taylor (R-T)不稳定表面波; 随着表面波的发展, 气流穿透表面波的波谷位置导致连续射流发生断裂. 正交分解(proper orthogonal decomposition, POD)方法可有效重构瞬时喷雾图像, POD模态表明近喷孔区域的低频和高频喷雾振荡分别由喷雾场的整体扩张/收缩过程和液块或者液雾团在迎风面的“撞击波”型运动引起, 而后者的形态属于受连续液体射流断裂前的R-T不稳定表面波影响而产生的行波结构, 其无量纲行波波长与韦伯数呈幂次律关系.
    In order to understand the fragmentation and atomization characteristics of the liquid jet in transverse gas film, a pintle injection element using air and water as simulants is designed. The two-phase flow large eddy simulation and backlight imaging are used to study the liquid-jet breakup process and spray-field dynamic characteristics in the nearorifice area of pinte injection element under the atmospheric environment. The primary fragmentation process of the liquid jet dominated by surface wave is obtained by large eddy simulation, which reveals the establishment process of the spray field in near-orifice area of the gas-liquid pintle injector. After the subsonic airflow leaves the slit, it expands and accelerates into supersonic state. Then the deceleration and pressurization phenomenon occurs once the supersonic airflow passes through the detached bow shock upstream of the liquid jet. The liquid jet bends downstream due to the difference in pressure between upstream and downstream, and the Rayleigh-Taylor (R-T) unstable surface wave appears on the jet windward surface. As the surface wave develops, the penetration of the wave trough by airflow causes the continuous liquid jet to fragment. Proper orthogonal decomposition (POD) method can effectively reconstruct spray snapshot. The POD mode shows that the low-frequency spray oscillation in near-orifice area is caused by the overall expansion/contraction process of the spray field, while the high-frequency one is due to the “impact wave” movement of the liquid block or liquid mist group on the windward side. The latter is produced by the R-T unstable surface wave before the jet breakup, and can be categorized as traveling wave structure. The dimensionless traveling wave wavelength has a power-law relationship with Weber number.
