Heat Transfer Enhancement by Addition of a Liquid Phase

Naturevolume 214page430 (1967) | Download Citation



EL'PERIN1 has shown that the addition of small quantities of liquid in atomized form to gases flowing across tube clusters can substantially increase the rate of transfer of heat from a surface. Recognizing the potential of the system investigated by El'perin, Acrivos et al.2 measured the rates of transfer of heat under more controlled conditions on an isolated cylinder. An air–atomized water mixture was used but only two flow conditions were explored in detail.
