| 摘 要： | 以不稳定性理论为基础为描述油滴破碎过程，以粘附、反弹／粘附和飞溅／附壁射流3个相互重叠的过程来描述喷雾碰壁，建立了燃油喷雾模型。将燃烧划分为低温着火、高温预混燃烧和相关火焰微元扩散燃烧3阶段建立了燃烧模型。开发了微机化三维模拟计算程序，在微机上对涡流室式柴油机的空气运动、喷雾和燃烧全过程进行了数值模拟。

| Abstract: | Based on instability theory the process of oil droplet breakup is described.The process of spray impingement is divided into three models:stick,rebound/stick and splash/ tangential jet.The combustion events in the swirl chamber diesel engine are broken into three phases:low temperature ignition,high temperature premixed combustion and coherent flamelet diffusion combustion.Thus a combustion model is established.The microcomputerized three -dimensional numerical calculation code is developed.In microcomputer the three- dimensional numerical simulation on the air motion,fuel spray and combustion in swirl chamber diesel engine is carried out. |
