The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.

2022年7月16日 · The Leidenfrost effect is a phenomenon where a vapor layer insulates a liquid from a surface, preventing rapid boiling. The insulating vapor makes liquid droplets hover over very hot surfaces. Similarly, a vapor layer insulates between very cold liquids and hot solids.

The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly.

2023年8月24日 · Liquid has a tendency to dance when on an extremely hot surface, especially when it's past its boiling point. As such, this occurrence is called the Leidenfrost effect, and it happens when...

The Leidenfrost effect is a phenomenon in which a liquid drop impinging on a surface significantly hotter than the boiling point of the liquid immediately forms an insulating vapor layer (approximately 0.06mm thickness at 433K [61,62] which decreases the heat transfer from the surface to the liquid and keeps the liquid from boiling rapidly.

Johann Gottlob Leidenfrost (27 November 1715 – 2 December 1794) was a German physician and theologian who first described the scientific phenomenon eponymously named the Leidenfrost effect. Personal life and career

2025年3月3日 · The Leidenfrost effect also works with other liquids, including oils and alcohol, but the temperature at which it manifests will be different. The phenomenon continues to fascinate physicists.

2018年11月16日 · In layman’s terms, the Leidenfrost Effect occurs when the surface in the proximity of liquid is hotter than the liquid’s boiling point. In the case of water this occurs when the surface is hotter than 200°C (twice the boiling point of water). How does the Leidenfrost Effect work? At 200°C part of each water droplet will vaporise.

2023年10月19日 · The Leidenfrost Effect can happen with any liquid that is poured over a surface whose temperature is higher than its boiling point. In fact, there are some interesting science experiments that make use of this amazing effect.

This review discusses how drops can levitate on a cushion of vapor when brought in contact with a hot solid. This is the so-called Leidenfrost phenomenon, a dynamical and transient effect, as vapor is injected below the liquid and pressed by the drop weight.
