Effect of interfacial phenomena on contact line heat transfer
Abstract
The stability and heat transfer characteristics of the contact line region of an evaporating thin liquid film was examined. The processes of heat, mass and momentum transfer in the film thickness region delta 10 to the -5th power m was measured. A miniaturized heat transfer cell on the stage of a microscope equipped with a scanning microphotometer was used. The interfacial concepts of disjoining pressure, spreading pressure, fluid microstructure and surface tension are used to analyze the transport processes and to develop a macroscopic suction potential model for the integral heat sink.
