利用混合破碎模型对涡流室内喷雾过程的三维数值模拟

Three-Dimensional Numerical Simulation of the Spray Process in Swirl Chamber with a Hybrid Breakup Model

利用已开发的大型流体计算软件包 ＥｎｇｉｎｅＣＦＤ－Ⅱ对涡流室式柴油机内的喷雾过程进行了三维数 值模拟。作者借鉴ＷＡＶＥ破碎模型的优点，进一步完善了ＴＡＢ破碎模型，使用混合模型来描述不同阶 段的油滴破碎过程。模拟结果与试验数据基本一致。

With the newly developed software EngineCFD-Ⅱ,three-dimensional numerical simulation of the spray process in swirl chamber was carried out. According to WAVE model,the original TAB model in KIVA-Ⅱis modified,the droplet's breakup process is simulated with a hybrid model which uses both TAB and WAVE model in different period. The numerical results is accordant with testing result.
