Measurement of the interfacial temperature jump during steady-state evaporation of a droplet

Abstract

Evaporation is an important phenomena that occurs in a wide range of natural and industrial processes. Although this phenomena has been a subject of research for many years, it is still not fully understood.\u3cbr/\u3eExperimental results of the last few decades seem to contradict with each other, and with the theory which describes this process, e.g. the kinetic theory of gasses (KTG) and non-equilibrium thermodynamics (NET). Temperature jumps of about 3.2-8.1oC at the interface of a steady state evaporating water droplet\u3cbr/\u3eat a pressure of about 245 Pa were measured . In order to determine whether this temperature jump exists and what influences this temperature jump, an experimental setup has been developed and the results are compared to theory
