场协同原理评价指标的定性分析和定量探讨

Qualitative Analysis and Quantitative Discussion of Index for Field Synergy Principle

介绍了场协同原理,对其评价指标进行了探讨,分析了5种评价方式(简单算术平均角、体积加权平均角、天量模平均角、模点积平均角及积分中值角),以空调器强化表面为例,进行了三维数值模拟,分别按5种方式进行了协同角的计算比较,计算结果表明:5种协同角整体变化趋势相似,能够反映速度场和温度场的协同性.定性分析表明,模平均角不仅物理意义明确,考虑因素全面.

Field synergy principle is introduced in the paper, of which the index is discussed, and several methods of field synergy angle are analysed, three dimension numerical simulation is conducted on heat exchanger surface, synergy angles are calculated and compared based on five methods .The result shows that their whole tendy is simular, and indicates the synergy between velocity field and temperature field qualitative analysis shows module avergy angle has not only the clear physical meaning but also has more considerations.
