Краткое описание

The purpose of the present study is to investigate the flow resistances and heat transfer characteristics of V-bent circular fin-tube heat exchangers. Four types of V-bent fin in which the fin areas are identical but the bent portions are different have been tested numerically. The heat transfer, pressure drop, fin temperature, fin efficiency, and shear stress are discussed. With an increase of 37% in the area of the V-bent portion, the heat transfer coefficient increases by up to 32% in the present test range.
