摘要
气力输送管道中颗粒群呈螺旋状前进的运动特点与风机预旋现象有密切联系,应用流体流动的最小阻力原理,分析风机预旋现象的产生原因及其对气固两相流管道中颗粒群运动的影响。
The spiral movement of the pellets in pneumatic conveying pipeline has close relationship with pre-spiraling phenomena of the blower. Using the minimum resistant principle of the fluid, the paper has analyzed the cause of pre-spiraling phenomena of the blower and impact to pellets movement of air-solid phase flow pipeline.
