摘要:
在大气环境下，以水为介质，采用PDPA和高速动态分析系统，针对直流撞击式喷注单元的雾场结构进行试验研究，获得了雾化液滴速度分布、粒径分布等试验参数。从液滴运动及液滴大小分布的角度针对撞击雾化液膜破碎成液滴的过程进行了分析，发现水平面上雾化液滴的径向速度以原点为中心对称，且随离原点距离增大而增大；初始雾化阶段的粒径大小分布则与径向速度分布相反。分析认为是液膜运动过程赋予了雾化液滴的初始速度,并影响了初始雾化液滴的分布特性。
Abstract:
The experimental study on atomization formation and size distribution of water droplets from the impinging liquid jets was executed in atmosphere environment by using PDPA and high speed dynamic analysis system. The movement and the size distribution of droplets were analyzed. It is found that the radial velocity of droplets on horizontal plane is centrosymmetric and increases as the increasing distance from the center to the measuring point. The size distribution of droplets in the initial stage of atomization is contrary to that of radial velocity. It is believed that the initial velocity of atomization droplets and the size distribution of droplets during the initial stage of atomization are both influenced by the movement of liquid sheet.
