Experimental study of heat transfer in an evaporating meniscus on a moving heated surface
Abstract
A stable meniscus is formed by a circular nozzle dispensing water over a heated circular
face of a rotating cylindrical copper block. The nozzle is offset from the axis of rotation of
the copper block and thus a moving meniscus is formed on the surface. The water flow
rate, heater surface temperature, and the speed of rotation are controlled to provide a
stable meniscus with continuous evaporation of water without any meniscus breakup. The
study provides an important insight into the role of the evaporating liquid-vapor interface
and transient heat conduction around a nucleating bubble in pool boiling.
