中文摘要:

为热转移改进基于地协同作用的原则, laminar 流动地里的物理数量协同作用的概念根据在液体和试管墙之间的对流的热转移的物理机制在现在的学习被建议。在液体粒子的物理数量之中的协同作用规定被建立反映在协同作用角度和热转移改进之间的关系的公式揭示。提高热转移并且减少流动抵抗的物理性质,直接与协同作用角度 α , β , γ , φ , θ 和 ψ 被联系,也被解释。而且,在物理数量之中的协同作用的原则被热转移和流动的计算数字地在一个薄插入内推柱体的试管验证,它可以为更好的热转移联合起来和高效率的热 exchanger 指导最佳设计。

英文摘要:

Based on the principle of field synergy for heat transfer enhancement, the concept of physical quantity synergy in the laminar flow field is proposed in the present study according to the physical mechanism of convective heat transfer between fluid and tube wall. The synergy regulation among physical quantities of fluid particle is revealed by establishing formulas reflecting the relation between synergy angles and heat transfer enhancement. The physical nature of enhancing heat transfer and reducing flow resistance, which is directly associated with synergy angles α,β,γ,φ,θ and ψ; is also explained. Besides, the principle of synergy among physical quantities is numerically verified by the calculation of heat transfer and flow in a thin cylinder-interpolated tube, which may guide the optimum design for better heat transfer unit and high-efficiency heat exchanger.
