Why water skitters off sizzling surfaces – and how to stop it

nature video published this video item, entitled “Why water skitters off sizzling surfaces – and how to stop it” – below is their description.

Water droplets on very hot surfaces bounce and skitter around on a thin cushion of water vapour. This phenomenon is known as the Leidenfrost Effect and it’s something that engineers often want to avoid as it makes water-based cooling systems less efficient.

Now, researchers in Hong Kong have put forward a newly designed surface intended to prevent the bouncing and skittering of the Leidenfrost Effect.

In This Story: Hong Kong

Hong Kong, officially the Hong Kong Special Administrative Region of the People’s Republic of China (HKSAR), is a metropolitan area and special administrative region of the People’s Republic of China on the eastern Pearl River Delta of the South China Sea. With over 7.5 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is one of the most densely populated places in the world.

Hong Kong became a colony of the British Empire after the Qing Empire ceded Hong Kong Island at the end of the First Opium War in 1842. The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898. The whole territory was transferred to China in 1997. As a special administrative region, Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of “one country, two systems”.
