Characteristic of water vapor condensation heat transfer on plate condenser using aluminum plates

Abstract

The spray flash desalination system has attracted attention because of its application in ocean thermal energy conversion plants. The spray flash desalination system, which is composed of a flash chamber, plate condenser, fresh water tank, and vacuum pump. In this study, the new herring-bone aluminum plate was configured and surface treated the plate by the anodic oxidation method. We measured the overall and condensation heat transfer coefficients. The experiment shows that the overall heat transfer coefficient is increasing with an increase in cold water velocity and the condensation heat transfer is also increasing with an increase in water vapor velocity.
