摘要: 以T型管道为试验平台, 利用压缩空气输送直径为1. 2mm的沙粒进行气力输送试验。在改变发送流量和发送压力的条件下, 利用F LUENT软件对气力输送过程进行数值模拟分析, 得到分支管道中压降与气固两相体积分数的变化。数值模拟结果表明, 单位长度管道内压降与发送流量和发送压力成正比; 管道底部固相颗粒体
积分数与发送流量成反比, 与发送压力成正比; 管道底部气相体积分数与发送流量成正比, 与发送压力成反比。数值模拟结果与试验结果相符, 为气力输送的进一步研究提供了相关依据。

Abstract: The pneumatic transmit experiments with the size of sand of 1.2 mm were carried out with compressed air as pumped in the T pipeline experimental bench. Numerical simulation analysis is carried out of the pneumatic transmit process under different condition of the transmission flow and pressure, whereas the change of pressure drop and gassolid two phase volume fraction in branch pipe was achieved. Numerical simulation results show that, pressure drop is proportional to the transmission flow and pressure in the lower part of the pipe, whereas particle volume fraction is inversely proportional to the transmission flow but proportional to transmission pressure. Gas volume fraction is proportional to flow, but it is inversely proportional to pressure. The simulation results are in good accordance with the experiment results. The study provides relevant basis for the further research of the pneumatic conveying.

Key words: Pneumatic conveying, Numerical simulation, FLUENT software, Pressure drop, Volume fraction
