| Outline of Final Research Achievements |
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.
