CONVECTIVE HEAT TRANSFER CHARACTERISTICS OF OVAL FIN-CIRCULAR TUBE HEAT EXCHANGER
타원형휜-원형관 열교환기의 강제대류 열전달 특성
Abstract
The purpose of the present study is to investigate the flow resistance and the heat transfer characteristics of oval fin-tube heat exchanger. Six kinds of oval fin having the same fin area and the different diameter ratio tested numerically. Test data for the heat transfer, pressure drop and fin temperature were shown and discussed. The pressure drop and heat transfer increased for increasing the oval fin diameter ratio(diameter of span-wise direction to diameter of longitudinal diameter) up to 50% and 45% respectively.
