Mixed Convection Heat Transfer from Horizontal Cylinders in the Crossflow of a Finite Water Layer

Heat transfer measurements and flow visualization studies have been performed for a single horizontal cylinder, a single row of six horizontal cylinders, and two rows of 13 horizontal cylinders submerged in an open channel flow. Regimes associated with free convection, combined convection, and forced convection have been delineated, and the effects of finite boundaries have been resolved. For a restricted set of space ratios, correlations of heat transfer data have been developed for the combined convection regime.
