论文摘要
通过偶然性在清洁或填充厨房水槽中的药品或液体小瓶时，观察到一系列引人入胜的流动特征。在这里，我们介绍了在新的几何布置中由水片形成的开放式倒钟和钟形的流动结构，迄今未知。当层流在边缘较大或类似直径的小瓶中撞击液体表面时，会形成倒置的开放水钟，随着流量的增加，该倒流逐渐将其逐渐变成平坦的水板变成经典的水铃。倒的水铃结构通过形成水脊而瓦解，最终分解成不同尺寸的液滴。
A range of fascinating flow features was observed while cleaning or filling the medicine or liquid vials in the kitchen sink by serendipity. Here, we present the formation of an open inverted bell and bell-shaped flow structures formed from the water sheet in a new geometric arrangement, hitherto unknown. When a laminar jet impinges on the surface of the liquid in the vial of marginally larger or similar diameter, an inverted open water bell is formed, which gradually changes into a flat water sheet to a classical water bell as the flow rate is increased. The inverted water bell structures disintegrate by forming water ridges which finally break down into different sizes of droplets.
