采用激光分幅全息技术观察到了直径为0.4mm液体射流上的表面波从小到大,最后导致液体破碎的发展过程。本文所得出的基本结论是:液体在雾化初始阶段的破碎起因子扰动波,扰动皮由表及里,在周向与轴向不断发展,首先将射流撕裂成大液滴,之后再进一步破碎成小液滴。液体射流破碎后的液滴尺寸往往大于初始扰动波长。
Using laser fractional holographic technique, the development of liquid waves with a diameter of 0.4mm on small to large surface waves was finally observed. The basic conclusions drawn in this paper are as follows: the disturbing wave of the breakage factor of liquid in the initial stage of atomization, the disturbance skin from the surface and the inside, the continuous development in the circumferential and axial direction, the first jet tearing into large droplets, Broken into small droplets. Droplet size after the liquid jet is broken is often larger than the initial perturbation wavelength.
