Comments to the Application of Enhanced Boiling Surfaces in Tube Bundles
要約
Use of specially enhanced boiling surfaces can greatly increase heat transfer rates at low boiling side temperature differences. However, proper utilization of these surfaces in tube bundles requires an understanding of the tube bundle boiling mechanisms plus some basic data to define surface factors and nucleate boilingconvective boiling relationships. Single tube data cannot be used alone to design enhanced tube bundles. Adjustments must be made for bundle effects through the use of circulation boiling concepts. The amount of enhancement for bundles theoretically must be less than for single tubes, but can still be great enough to make such surfaces economically attractive in carefully selected applications.
