摘要

根据层析技术原理，对喷雾雾滴粒径和浓度的空间分布开展了研究，并编制了喷雾粒径和浓度层析计算程序.对给定粒径和浓度空间分布的喷雾场，根据脉动法测量原理在计算机上仿真了雾滴粒径和浓度的线投影值，根据仿真的投影值重建了雾滴粒径和浓度的空间分布，重建结果与给定的分布结果完全吻合.在喷雾实验台上用光脉动法装置测量了喷雾雾滴粒径和浓度的线投影值，并用编制的程序对喷雾雾滴粒径和浓度的空间分布进行了层析计算.

Abstract

Spatial distribution of spraying drop size and concentration are important parameters to investigate spraying field.Tomography measurement is shown to be an advantaged method for studying drop size and concentration distribution of nozzle atomization.Based on tomography measurement theory and fluctuation method

tomography algorithm program for reconstructing spatial distribution of spraying drop size and concentration was compiled.In order to test the program

computer simulation was used.According to tomography principle

simulation experiment was divided into two steps.First

the linear projection data of drop size and concentration were simulated with a given spraying field

and then with these simulated data

spatial distribution of drop size and concentration were reconstructed with the program compiled by the authors.The simulation result showed that reconstructed distribution field coincided with the given field.The program was used for reconstructing the spatial distribution of spraying field with experimental data obtained by the experimental platform of fluctuation method.
