摘要: 研究了一種在太空生產(chǎn)中的材料輸送方式.通過數(shù)值仿真得出以下結(jié)論:采用管道空氣輸送能夠減小壓力損失從而提高能源利用率;對于不同種類的被輸送物質(zhì),都可以找到合適的輸送條件,既能夠最大限度地減小動力,又不至于因為動力不足而無法輸送;管道內(nèi)粒子的運動軌跡幾乎完全取決于氣流. This paper aims to find a workable way of transportation of powder in outer space. The results of simulation indicate that in outer space, air transportation of powder in pipe can reduce the pressure loss and improve the utilization ratio of energy sources. For various materials, we can find a suitable condition for the transportation. Besides, the track of powder in pipe almost depends on the airflow completely.
