摘要
本文分析了潜热型功能热流体强化换热的物理机制，并基于等效比热模型，对等热流条件下圆管内该类流体层流流动换热强化的各因素进行了敏感性分析．同时，改进了内部流动传统的Ｎμ定义。
This paper analyzes the convective heat transfer enhancement mechanism of latent functionally thermal fluid. By using the effective specific heat capacity model, the influence of each factor affecting the heat transfer enhancement of laminar flow in the tube with constant heat flux is analyzed. In addition, a modification of the conventional Nusselt number definition for internal flow is introduced to describe the degree of heat transfer enhancement for latent functionally thermal fluid more effectively.
