Mass transfer on nucleate boiling surfaces using the electrochemical method

摘要

The mass transfer behavior of electroactive solutes from bulk solution to a metal surface (Alloy 800) under nucleate boiling conditions was investigated using a novel pool-boiling device. The electrochemical method was successfully used to measure the limiting current on a boiling surface for the first time. The effects of heat flux and surface roughness on mass transfer were studied. A correlation describes the effect between mass transfer and heat flux in boiling condition with the consideration of surface roughness is proposed and proven to be valid.
