摘要: 通过分析和数值模拟,证实了流体在新型翅片下形成的流道内呈混沌状态流动,混沌流在低Re下即可产生较强混合效果,提高了传热和抗结垢能力。新型翅片为将混沌流概念应用于板翅换热器提供有益的探索。

Abstract: Analysis and the numerical simulation has confirmed that the flow is of the chaotic advection in the flow channel of the new fin. The chaotic advection results in stronger mixing under low Re, and thus enhances the heat transfer and anti-scaling ability. The new fin provides the beneficial exploration to the concept of chaotic advection which applies to the plate-fin heat exchanger.
