著者:松尾伸彦、有馬博史、岡本明夫、執行啓太、池上康之題名:プレート式蒸発器の表面微細加工によるアンモニア沸騰熱伝達促進発表情報:第47回日本伝熱シンポジウム 巻: G335キーワード:Heat transfer enhancement, Heat transfer coefficient, Ammonia, Plate heat exchanger, Micro grooved surface概要:抄録:The aim of this study is to examine what the optimum surface condition for boiling heat transfer of the plate type evaporator for OTEC. In this study, the measurement of heat transfer coefficient using three different surface plates was performed. The first surface type is flat surface (S1), the second one is vertical grooved surface (S2) and the third one is horizontal grooved surface (S3). The result shows that, the boiling heat transfer coefficient of both grooved surface was larger than that of flat surface. Especially the effect of heat transfer enhancement using grooved surface appeared notably in the nucleate boiling region.英語フィールド
