摘要: 叙述了对流换热中的场协同强化原则,对流换热中速度场与温度场的协同能够提高换热系数,换热器中冷、热流体温度场间的协同能够提高换热器的效率。此外,还从换热系数和换热器两个层次上讨论了场协同强化原则在提高换热器性能方面的应用。

Abstract: the principle of field-coordinated enhancement of heat convection is presented that the better coordination between the velocity and temperature fields will lead a higher convective heat transfer coefficient, and the better coordination between the temperature fields of hot and cold fluids will lead a greater effectiveness of heat exchangers. Furthermore, applications of the principle of field-coordinated enhancement on upgrading the performance of heat exchanger are discussed.

Key words: Field coordination, Heat exchanger, Heat transfer enhancement
