Abstract

The purpose of the present study is to investigate the flow resistance and the heat transfer characteristics of V type circular fin-tube heat exchanger. Four kinds of V type fin having the same fin area and the different span wise angle 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 decreasing the span wise angle up to 58% and 25% respectively.
