本文概括介绍了作者近期对激光测雾技术本身的研究结果,包括液雾特性(索太尔平均直径,液滴尺寸分布指数)随喷嘴压力降的变化,液雾特性随空气流速的影响,遮光率随喷油流量(喷嘴压力降)变化的经验概括式,遮光率对所测液雾特性的影响,所测的液雾特性随激光束的轴向、径向、角向位置的变化等。最后指出在激光散射测雾技术上急需解决的一些问题。
This article summarizes the author’s recent research results of the laser fogging technology itself, including the characteristics of the liquid mist (Sauter mean diameter, droplet size distribution index) with the nozzle pressure drop changes, the liquid mist characteristics with the air velocity, light shading The rate of change with the fuel injection flow (nozzle pressure drop) experience summarized, shading rate of the measured liquid mist characteristics, the measured liquid mist properties with the laser beam axial, radial, angular position changes. Finally, some problems that need to be solved urgently in laser scattering fogging technology are pointed out.
