摘 要: 本文对水股跌落水塘的掺气水流模拟过程中,水流挟气浓度、气泡尺寸、挟气水流长度的缩尺效应进行了讨论,提出了一个挟气浓度的测量方法──集气采样法,其原理简洁合理,设备简单,操作方便,结合工程实际阐述了类似的掺气水流模拟所应注意的问题。 Abstract: This paper discusses the scale effect of the aeration density,bubble size and length of aerated flow. An aeration density measuring method-air collecting sampling method is presented. The method has the advantage of concise and reasonable principle, simple instrument and easy operation. Concrete project is used as an example to show the problems to which attention should be paid in similar aerated flow simulation.
