摘要

为提高用于喷雾冷却的压力旋流喷嘴的雾化性能

优化喷嘴的结构参数

基于流体体积函数法(VOF)对旋流喷嘴进行了仿真分析

采用正交试验的方法分析各参数对液膜厚度和雾化锥角影响的显著性

并对喷嘴结构参数进行了优化。结果表明:出口长度

、出口直径

和旋流孔数

对喷嘴雾化性能的影响较显著

旋流室高度

对雾化性能的影响较小;增大喷嘴出口长度

能够减小液膜厚度和雾化锥角;增大出口直径

能够增大液膜厚度和雾化锥角;增大旋流孔数

会使液膜变厚

雾化锥角变小;增大旋流室高度

会使液膜厚度先减小后增大

雾化锥角减小;当出口长度

为2 mm

出口直径

为10 mm

旋流室高度

为16 mm

旋流孔数

为6时

雾化性能最佳

相较于原模型雾化锥角增大了16.8%

液膜厚度减小了32.4%。

Abstract

In order to improve the atomization performance of the pressure swirl nozzle used for spray cooling and optimize the structural parameters of the nozzle

simulation analysis of the swirl nozzle based on the volume-of-fluid function (VOF) method was carried out

and orthogonal tests were used to analyze the significance of the influence of each parameter on the thickness of the liquid film and the spray angel of atomization

then the structural parameters of the nozzle were optimized. Results show that the outlet length

outlet diameter

and the number of cyclone holes

have a more signi

ficant effect on the atomization performance of the nozzle

and the height of the cyclone chamber

has a smaller effect on the atomization performance. Increasing the nozzle outlet length

can reduce the liquid film thickness and atomization spray angel; increasing the outlet diameter

can increase the liquid film thickness and atomization spray angel; increasing the number of cyclone holes

will make the liquid film become thicker and the atomization spray angel become smaller; increasing the height of the cyclone chamber

will make the liquid film thickness decrease firstly and then increase

and the atomization spray angel decrease. When the outlet length

is 2 mm

the outlet diameter

is 10 mm

the height of the cyclone chamber

is 16 mm

and the number of cyclone holes

is 6

the atomization performance is optimal. Compared with the original model

the atomization spray angel of the optimized nozzle is increased by 16.8%

and its liquid film thickness is decreased by 32.4%.
