矿井和工厂厂房通风以及除尘净化设备的风流流动过程(排烟排尘过程)和动力阻力特性常包括一些未知因素,往往难于用已有的方程加以解算。这时在模型上进行试验研究比在生产条件下进行试验研究具有很多的优越性,它可以节省人力、物力,试验条件容易控制,不受生产条件的影响,而且容易观测其物理过程,数据也较准确。本文拟就我室实验结果,着重介绍实验中的相似方法。
Ventilation of mines and factory buildings, as well as dust removal and purification equipment (exhaust and dust removal process) and dynamic resistance characteristics often include unknown factors and are often difficult to solve using existing equations. At this time, the experimental research on the model has many advantages over the experimental research under the production conditions. It can save manpower and material resources, the test conditions are easy to control, the production conditions are not affected, and the physical process is easy to observe. The data More accurate. This article intends to my laboratory results, focusing on the experimental similar methods.
