摘要 用三维计算流体力学软件模拟了汽油缸内喷射的静态喷雾特性 ,研究了燃烧室压力、初始液滴直径和喷雾锥角对喷雾特性的影响 ,并与试验结果进行了比较。研究结果表明 :燃烧室压力。 This paper simulates the gasoline direct injection spray in the cylinder and investigates the effects of chamber pressure,initial droplet diameter and spray cone angle on spray structure and configuration.Computational results are compared with experimental ones.It concludes that chamber pressure,initial droplet diameter and spray cone angle have significant effects on spray structure and configuration.
