新一代高效内燃机对燃油喷射和雾化提出了更高的要求,喷嘴处的不稳定空化流动会直接影响循环喷射量及喷雾燃烧过程.采用一种结合比耗散率ω方程的雷诺应力-尺度自适应(RSM-SAS)湍流模型、流体体积(VOF)法多相流模型和Zwart-Gerbera-Belamri(ZGB)相变传质模型,对轨压为60 MPa、环境压力为0.1 MPa条件下的喷嘴内空化两相流开展研究.基于Ω涡识别方法,解析了喷嘴内强涡旋和弱涡旋.针对涡量场和空化相分布的时空特性,分析了涡流演变和空化过程之间的联系.在此基础上,讨论了喷孔内多个横截面物理场的非定常特性,阐明了喷孔内涡偏心、涡变形和涡核进动等时空不稳定行为,揭示了涡核总压损失和压力波动特征.结果表明:喷射过程中喷嘴处存在强制涡旋、自由涡旋、剪切层涡和尾涡等复杂流体结构,并与空化存在强耦合导致流动不稳定,在喷孔前段易出现回流区,喷孔后段易形成空化并发展到喷雾区,从而对近场喷雾产生扰动.
