在强化传热的场协同原理的基础上，根据流体与固壁间对流换热的物理本质，分析了对流换热层流场中的物理量协同。通过反映强化传热机理的数学表达式，揭示了物理量之间的协同规律。分析了协同角α、β和γ对强化传热的影响。数值模拟验证了本文提出的物理量协同原理。
On the basis of field synergy principle for heat transfer enhancement, physical quantity synergy in laminar flow field of convective heat transfer is analyzed according to physical nature of convective heat transfer between fluid and solid wall. Synergy regulation among physical quantities is revealed by mathematical expressions reflecting mechanism of heat transfer enhancement. Characteristic of heat transfer enhancement, which is directly associated with synergy angles α, β and γ, is also analyzed. Numerical simulation is made to verify the principle of physical quantity synergy developed in the paper.
