摘要:
建立了垂直式水煤膏雾化试验装置,采用PIV(particle image velocimetry)及二次开发的图像处理软件对水煤膏雾化特性进行了测量,分析了水煤膏雾化颗粒测量的影响因素.PIV测量技术不仅可以用于流场测量,通过对PIV图像的二次处理还可以用于颗粒粒径的测量,为进一步研究水煤膏喷嘴的雾化性能提供了坚实的基础.结果表明,随着气膏质量比的增加,雾化平均粒径降低,当气膏质量比大于0.6时,雾化颗粒质量平均粒径降低的幅度很小.
Abstract:
To study the atomizing properties of the coal-water paste(CWP), a vertical atomizing test device is constructed. The atomization particle size and its distribution of CWP in the spray are measured with PIV measurement and newly developed image processing software. The influence factors of the measurement of CWP atomization particles are analyzed. It is valid not only to measure the fluid field, but also to measure the particle size distribution with PIV and its image processing software, creating a solid basis for further research of the nozzle atomizing properties of the CWP. The results show that atomization particle diameters decrease with increasing of gas to CWP mass ratio, and the decrease degree of atomization particle mass median diameter is very small under the condition of Mg/MCWP>0.6.
