采用激光双曝光全息干涉技术研究相互耦合的柴油机压缩温度场与喷雾场

Coupling Between Compression Temperature Field and Spray In A Real Diesel Engine by Laser Double Exposure Holographic Technique

为探讨柴油机缸内压缩温度场对柴油机喷雾过程的影响 ,采用激光双曝光全息干涉应用于柴油机缸内喷雾与压缩温度场的耦合过程。得到了温度场与浓度场耦合的全息干涉条纹 ,直观地显示了喷雾油束与温度场的形状。

The aim of this paper is to explore the effect of compression temperature field on spray process. The author has displayed the coupling process between compression temperature field and spray. The interferometry fringes are provided by laser double exposure holographic technique. The outline of spray and compression temperature is directly demonstrated. A new method has been developed for investigating and analyzing the transfer process of diesel combustion chamber.
