HOT SNOW
“Cold-physicist” Valery Kostyuk studied heat exchange and hydrodynamics of liquids in ultra-cooled environment

 

It is generally accepted that energy means fire, flame and heat. However, the absence of heat and flame can also be an energy resource, while boiling gases, liquefied at low temperatures can become such a source, which under some circumstances may become the only one possible. Valery Kostyuk, a Russian thermophysicist, is known rather as a “cold physicist”, as for many years he’d been supervising experiments of his fellow scientists and studied heat exchange and hydrodynamics of various liquids in extreme cryogenic, that is very cold conditions. Low temperatures lie within the range from the absolute zero – zero Kelvin (or -273.150C) – to 00C. Even a special scientific institution is established – the International Institute of Refrigeration, which for more than a century has been studying scientific and technical aspects of artificial cold generation and use and all devices and technologies within the specified temperature range: from refrigerators and heat pumps to cryophysics and cryogenics. “Cryogenics” means even lower temperatures, i.e. below 120 degrees Kelvin, the natural gas condensation temperature. Dr. Valery Kostyuk is a member of the Executive Committee of this Institute and his entire scientific biography is connected with cold in one way or another. Nitrogen, oxygen, hydrogen, neon, fluorine, ammonia and freons were made to boil at this institute (as a matter of fact, the experiments with fluorine were carried out for the first time in the world).
