Local heat/mass transfer distribution in a square channel with full and V-shaped ribs Academic Article uri icon

abstract

  • Naphthalene sublimation experiments have been conducted to study the turbulent heat/mass transfer characteristics of airflow in a square channel, in which two opposite walls are roughened with aligned arrays of full ribs and V-shaped ribs. The detailed distributions of the local heat/mass transfer coefficient on the ribbed walls and on the smooth walls are obtained. Results show that there are significant spanwise as well as streamwise variations of the local heat/mass transfer coefficient on the exposed surfaces of the ribbed walls in the oblique full rib and V-shaped rib cases. © 1993 Pergamon Press Ltd.
