S052013 Three-dimensional Flow Characteristic in Wavy Channel

Abstract

The corelation between the influence of the shape of wavy channel and pressure loss in the channel are investigated in this paper. The need for lightweight and spacesavig has driven the development of advanced heat exchanger. Among them, wavy passages are characterized by extended surface area/volum ratios that are often configured in plate-fin heat exchanger. However,optimum configulation is not found that formed the minimum recirculation regio at curved passage. In this research, the vortex structure of the secondary flow for two type of the passage was investigated.
