| 摘 要： | 根据现代热力学流与力的热力学线性唯象关系，导出了对流换热强度与流体中存在的各种内场及外场的关系，从唯象上阐明了降低热边界层厚度、增加流体优动和增加近壁面速度梯度的强化对流换热方法的物理机制。结果表明，强化对流换热的本质是控制内场和外场方向的协同，并从此可指导发展强化对流换热的新方法。

| Abstract: | The relationship of convective heat transfer intensity between internal fields in the fluid and applied external fields is derived according to the linear phenomenological relations of thermodynamic forces and fluxs. The three mechanisms for enhancing convective heat transfer,which are decreasing the thermal boundary layer thickness, increasing the interruption in the fluids and increasing the velocity gradient near a heat transfer wall, is clarified. The results show that the essence of enhancing convective heat transfer is the synergy between different fields in the fluid, and which can guides us to developing new approaches to enhancing convective heat transfer. |
