Effect of Interfacial Phenomena on Contact Line Heat Transfer-III.

Abstract

The heat transfer characteristics of the contact line region of an evaporating thin liquid film were studied experimentally and theoretically. The effects of composition and temperature gradients on surface shear were analyzed and the results were successfully compared with previously reported experimental trends. The use of a constant vapor pressure boundary condition allowed the relative effects of surface tension, composition and temperature on fluid flow to be mapped. A small heat transfer cell was designed, built and used on the scanning stage of a scanning microphotometer. The unique use of a microphotometer allows the microscopic details to be measured. Keywords: Evaporation, Heat pipes, Capillarity, Distillation, Silicon carbide films, Thermistors, Interfacial tension.
