| 摘 要： | 应用数字粒子图像测速技术对燃油喷雾进行了深入的研究。以可视化的测试结果为依据,提出了对燃油破碎雾化过程认识的新观点,即在喷射纵向上,把燃油雾化破碎分为初始破碎区和细化破碎区2个部分;在喷射横向上分为雾化核心区、过渡区和边缘区3个部分。研究发现燃油破碎的整个过程中出现了油团、油线、油云聚集体等燃油破碎单元。结合测试结果对上述燃油破碎单元的出现、发展和转变过程进行了深入分析。结果表明:油束雾化是一个连续渐变多状态混合叠加的过程。 |

| Abstract: | Using digital particle image velocimetry(DPIV) technique,the fuel spray and atomization mechanism were studied.On the basis of analyzing the visual image,authors set up a new standpoint to understand the fuel breakup atomization mechanism,ie authors divided the spray pattern into original breakup and fine breakup on the vertical direction,and divided the spray pattern into core part,transition part and outermost part on the horizontal direction.Fuel group,fuel string and fuel particle gather unit appeared during the process of fuel breakup.The process of appearance,development and variation of the fuel breakup element was analyzed deeply.It is safely to draw the conclusion that fuel atomization is a continuous,variable and miscellaneous process of multimode. |
