在层流换热场物理量协同原理的基础上,针对湍流零方程模型和k-ε两方程模型,建立了湍流换热的能量和动量协同方程,揭示了湍流换热流场中热流、质量流与流体流动驱动力之间的协同关系及其所反映的强化传热机理,将强化传热的场物理量协同原理由层流延展到湍流.通过圆管内置旋扭式螺旋片的强化传热计算分析,证明了湍流换热场物理量协同原理具有普遍性.因此,根据湍流换热流场的物理量协同关系,可对各种不同的管内强化传热元件和表面的换热性能和流动阻力进行分析比较,从而为提高传热单元或换热器的综合性能提供理论和设计依据.
Based on the synergistic principle of the physical quantities of the laminar heat transfer field, a turbulence-free equation and a k-ε two-equation model are established. The synergistic equations of energy and momentum for turbulent heat transfer are established. And the driving force of the fluid flow and the heat transfer enhancement mechanism reflected by it, the synergistic principle of field physical quantities of enhanced heat transfer is extended from laminar flow to turbulent flow.Through the heat transfer enhancement It is proved that the physical quantity synergy principle of turbulent heat transfer field is universal.Therefore, according to the physical quantity synergy relationship of turbulent heat transfer flow field, the heat transfer performance and flow resistance of various heat transfer elements and surfaces can be analyzed So as to provide theoretical and design basis for improving the overall performance of heat transfer unit or heat exchanger.
