熱交換器の設計に与える固体熱伝導の影響

抄録

Recently, CFD is widely used at the design process of a heat exchanger. Almost CFD including commercial software often apply constant temperature treatment for boundary condition on the wall in these cases. However, it is useless at the design process of the high performance heat exchanger. Therefore, it is necessary that Solid-Fluid Coupling Method considering the wall heat conduction is used in these cases. The purpose of this investigation is to establish the numerical method for fluid/solid interaction in the thermal fluids. In this study, Solid-Fluid Coupling Method considering solid heat conduction between cooling fluid and cooled fluid is offered a suggestion. In particular, it has proposed a method to specify the temperature at the fluid/solid interface in the passage of the heat exchanger.
