Abstract

In this paper, Y-shaped branch pipes are designed with one branch being unchanged and the other being changeable. Gas-Solid flow experiments of average particle diameter 2mm millet are carried out using compress air at horizontal Yshaped branch pipe. Resistance properties of each branch and the mutual resistance characteristics are described. The results show when the superficial gas velocity reduces, the pressure drop on each branch and the pressure drop differential value of the two branches decrease firstly, but when the superficial gas velocity reduces to deposition velocity, the respective pressure drop begin to rise. With the differential value rising of the angle between the changing branch and the main pipe, it is found that the pressure drop curve of each branch and the pressure drop differential value of the two branch are away from each other in high gas velocity zone, while become near in low gas velocity zone. Meanwhile, principal component analysis method is adopted to explore the importance of influencing factors and their correlation. The experimental consequence shows that the angle between the changeable branch and the main pipe, superficial gas velocity and the solids loading ratio are chief influencing factors.
