Heat Transfer Characteristics in Horizontal Fluid Layer with Honeycomb.

Abstract

Natural convection in a heated horizontal fluid layer have been studied experimentally and theoretically for many years. In industrial components such as boilers or reactors, heat and mass are sometimes transferred through a horizontal fluid layer, including the internal structures. The heat transfer characteristics was experimantally studied in the horizontal water layer, including honeycombs of different flow area reduction ratios. Large eddy motion was reduced with the honeycomb but the heat transfer rate through the layer could not be affected, even at the flow area reduction rate of 0.09. Further reduction of the flow area resulted in the nonuniform temperature distribution of the central fluid layer and depression of the heat transfer rate.
