当单个液滴落在温度超过某一临界值的炽热固体表面上时,液滴会像弹性球一样跳跃,并伴随着液滴表面蒸发而滴径逐步缩小.这种现象由J.G.Leidenfrost在1756年所发现,是物理学上著名的“球化态”奇异现象,称为Leidenfrost现象.出现此现象的热表面临界温度则称为 Leidenfrost温度(LF
When a single drop of liquid falls on a hot solid surface at a temperature above a certain threshold, the droplet jumps like a flexible ball and gradually decreases in droplet diameter as the droplet surface evaporates. This phenomenon was reported by JG Leidenfrost in 1756 The discovery is a well-known “ballistic” singularity known as the Leidenfrost phenomenon, where the hot surface critical temperature is called the Leidenfrost temperature (LF
