本研究では，微細翼型チューブ熱交換器の気相側伝熱性能のさらなる向上と翼型チューブ内冷媒側伝熱性能の向上を目的とする．そこで，スリット付き拡張前後縁部を有する翼型チューブ熱交換器の気相側伝熱性能を数値解析的に検討し，熱交換器としての高性能化を図った．また，翼型チューブ内の冷媒の熱伝達特性の向上を目指し，まずは蒸発部と凝縮部を有するループ式ミニチャンネル内の仮想的にポンプ駆動された冷媒の熱流動について検討を行い，相変化伝熱に関する基礎特性を数値解析的に確認した．その結果，熱交換器の高性能化に繋がる指針を得た．
The objectives of this study are further improvement of air-side heat transfer performance of the micro airfoil-shaped tube heat exchanger and enhancement of refrigerant-side heat transfer performance in the airfoil-shaped tube. Therefore, numerical simulation was performed on pressure drop and heat transfer performance of a heat exchanger using airfoil-shaped tubes having extended leading and trailing edge section with slits. Moreover, the developed phase change simulation was applied to investigate the heat transfer characteristics of refrigerant in a pump-driven looped minichannel having heating and cooling sections. The results revealed important guideline for developing high performance heat exchanger.
