Abstract
This lecture focus attention on the heat transfer and crisis phenomena in falling films of cryogenic liquid. Experimental results on behavior of a laminar-wavy liquid film at its intense evaporating under conditions of a gravity flow over a heated vertical surface are presented. A brief review of previous investigations is also given. Thin liquids films are utilized as an important component in various heat transfer processes because of their high heat transfer rate at low feed rates and with small temperature difference. Evaporators employing such characteristics are widely found in refrigeration systems, petrochemical and distillation plants, air and natural gas liquefying facilities.
