Solid-Liquid Mass Transfer under Flow Boiling Condition

Abstract

The study of mass transfer behavior under a flow boiling condition has not been reported due to the complexities of the phenomenon and experimental difficulties. In the present study, a novel high temperature and pressure experimental flow loop as well as measuring techniques were developed to determine the mass transfer coefficient under the flow boiling condition to a level that no one else has achieved according to open literature. A new mass transfer correlation was proposed and proven to be suitable for representing the flow boiling mass transfer behavior. This work will provide a good base for further flow boiling mass transfer studies.

Review—Factors Influencing Sulfur Induced Corrosion on the Secondary Side in Pressurized Water Reactors (PWRs)

“…The flow boiling condition simulates the real SG service condition which is similar to a nucleation boiling surface, i.e., the temperature inside SG tubing is as high as 300 • C. Flow boiling is a complex condition involving elevated pressure and temperature which generate vapor and results in the flowing vapor-liquid two phases. Recently, Chen et al 173 established a novel experimental setup to simulate flow boiling condition and to study the solid-liquid mass transfer under flow boiling conditions. In such condition, the electrochemical process is governed by mass transfer, which has not been investigated previously.…”
