Effect of Interline Heat Flow Parameter on Contact Line Heat Transfer
Abstract
A circular heat transfer cell was designed and fabricated to study fluid flow and change of phase heat transfer in the contact line region. The cell incorporates the use of ellipsometry and interferometry to measure ultra- thin film thickness profiles, which give the local pressure field for fluid flow. In addition, the total fluid flow rate and, therefore, the integral heat sink of the evaporating meniscus can be measured. A theoretical equation that includes the effects of capillarity, disjoining pressure, gravity and temperature on the thin film heat transfer process has been developed and used. Keywords: Capillary pressure, Evaporation, Disjoining pressure, Thin liquid film, Interfacial phenomena.
