概要 This paper summarizes experimental and theoretical studies that have been performed in our laboratory to enhance condensation heat transfer on horizontal tubes and tube bundles by use of fins. Use of ...a drainge strip is proved to be very effective in further enhancing condensation heat transfer on the horizontal finned tube. Effects of fin geometry and tube arrangement on the condensation heat transfer performance of the tube bundle are investigated. A theoretical model is proposed to predict the performance of a bundle of horizontal tubes with flat-sided annular fins. The model is used to optimize the fin geometry for given operating conditions of a shell and tube condenser. It is shown that the highest heat transfer performance is provided by the flat-sided fin tube with fin dimensions close to the theoretically determined optimum values.続きを見る
