摘要
通过实验研究了在气流冲击下水面的凹陷情况,并通过理论计算予以解释.结果表明凹陷的体积和深度主要与气流速度、玻璃管内径和玻璃管底部到水面上的距离有关的结论.
The volume and depth of the air pocket produced by vertical air jet from a straw were investigated theoretically and experimentally.The volume and the depth were mainly determined by the flow rate of the air jet,the inner radius of the straw,and the distance between the open tip of the straw and the water surface.
