在 laminar 热转移的地里基于物理数量协同作用的原则,并且根据零个方程和 k- 的模型的意见吗?为狂暴的流动的二个方程,为精力和动量的协同作用方程在狂暴的热转移的保存被建立。在它反映的热转移改进的热流动,集体流动和液体驱动力,和机制之中的协同作用规定被揭示。热流动地里的物理数量的协同作用原则从 laminar 流动被扩大到狂暴的流动。原则被验证由在一个试管与的热转移改进的计算通用一螺旋状的扭曲的磁带的 insert。因此,相应于在狂暴的流动地,对流的热转移的表演和为有不同的热转移部件和表面的试管的流动抵抗里的物理数量之中的协同作用关系能通过理论、计算的分析被比较,它从而为设计热转移单位和热 exchangers 提供指导。
Based on the principle of physical quantity synergy in the field of laminar heat transfer, and according to the models of zero equation and κ-ε two equations for the turbulent flow, the synergy equations for both energy and momentum conservation in the turbulent heat transfer are established. The synergy regulation among heat flux, mass flow and fluid driving force, and the mechanism of heat transfer enhancement it reflects are revealed. The synergy principle of physical quantity in the thermal flow field is extended from laminar flow to turbulent flow. The principle is verified to be universal by the calculation of beat transfer enhancement in a tube with an insert of helical twisted tape. Thus, corresponding to the synergy relation among physical quantities in the turbulent flow field, the performance of convective heat transfer and flow resistance for the tubes with different heat transfer components and surface can be compared through theoretical and computational analysis, which thereby provides a guidance for designing heat transfer units and heat exchangers.
