摘要
拉瓦尔喷嘴进口直径、喉管直径、喷管出口直径、收缩段长度,扩张段长度对于其雾化效果都有一定的影响.本文采用无量纲量的方法,通过Fluent对拉瓦尔喷嘴结构中喉管直径、喷管进口直径、收缩段长度三个变量配合的多种工况进行仿真研究,从而得到拉瓦尔喷嘴最优的结构参数.
The diameter of the inlet of the Laval nozzle,the diameter of the throat,the diameter of the outlet of the nozzle,the length of the contraction section,and the length of the expansion section have certain effects on its atomization effect.In this paper,a dimensionless quantity method is used to simulate and study a variety of working conditions with three variables of throat diameter,nozzle inlet diameter,and contraction length in the Laval nozzle structure by Fluent to obtain the optimal structure of the Laval nozzle parameter.
