气固两相流压降探讨计算

Calculation of Gas-solid two-Phase Flow Pressure Drop

人类很早就开始利用运动的空气(即风力)来驱动物体,如风车舂米磨面,风帆船运输等。随着科学技术和工业的发展,尤其是工业革命以来,用流动气体来输送固体得到了广泛的应用。18世纪末和19世纪初出现了管道的气力输送,20世纪初,在美国、俄罗斯、德国和欧洲许多国家气力输送邮件得到普遍的应用。对于气体输送固体的工艺要求越来越高,尤其是工艺设备和流程的选取、设计以及系统的操作管理的可靠性。

Humans have long used the moving air(ie wind)to drive objects,such as windmills,glutinous rice,and sailboats.With the development of science and technology and industry,especially since the industrial revolution,the use of flowing gas to transport solids has been widely used.At the end of the 18th century and the beginning of the 19th century,the pneumatic transmission of pipelines appeared.In the early 20th century,the power transmission of mail in the United States,Russia,Germany and many European countries was widely used.The process requirements for gas transport of solids are increasing,especially the selection and design of process equipment and processes,and the reliability of operational management of the system.
