多分散液态气溶胶粒子瞬时线源的扩散—沉积模式

A DIFFUSION-DEPOSITION MODEL FOR INSTANTANEOUS LINEAR SOURCES OF POLYDISPERSITY LIQUID AEROSOL PARTICLES

针对飞机喷洒液态杀虫剂的研究需要，本文建立了排放呈多分散液态气溶胶粒子的高架有限瞬时线源的扩散—沉积模式。研究中发现，蒸发效应对液态气溶胶粒子的扩散及沉积量影响很大，相应的固态气溶胶粒子的高架有限瞬时线源的扩散—沉积模式只是它的一个特例。本文还讨论了液态气溶胶粒子的重力沉降速度的预报方法。

To meet the need of the study of spraying liquid insecticide by aeroplane, a diffusion-deposition model for elevated limited instantaneous sources of polydispersity liquid aerosol particles was formulated. The studies show that for liquid aerosol particles, evaporation effect has a large influence on the amount of diffusion and deposition, and the corresponding model for solid particles is merely a particular case of the present one.For the more, the methods for predicting the gravity deposition velocity of liquid aerosol particles are also discussed in this paper
