OpenFOAMを用いた翼型熱交換器の伝熱解析

抄録

To improve the energy efficiency, it is important to increase the heat transfer coefficient per flow resistance. Previous studies have reported that the airfoil tube provides a better heat transfer coefficient per flow resistance than the circular tube. However, there are not many studies on heat transfer in the case of multiple configurations of airfoils. In this study, a comparison of the heat transfer efficiency of a staggered arrangement of airfoil tubes and circular tubes is performed using numerical analysis. Under the conditions of the present analysis, both the pump power and the total heat transfer of airfoil tubes are superior to those of circular tubes.
