Discussion on the extensions of the entransy theory

Science China Technological Sciences, 2017
In this paper, the preconditions for the extensions of the entransy theory are summarized and discussed. As the physical meaning of entransy is the “potential energy” of thermal energy, the concepts and analyses method of the entransy theory can be extended based on the viewpoint of potential energy.

Optimization of fin geometry in heat convection with entransy theory

Chinese Physics B, 2013
The entransy theory developed in recent years is used to optimize the aspect ratio of a plate fin in heat convection. Based on a two-dimensional model, the theoretical analysis shows that the minimum thermal resistance defined with the concept of entransy dissipation corresponds to the maximum heat transfer rate when the temperature of the heating ...

Constructal study on a cylindrical heat source based on entransy theory

Chinese Science Bulletin, 2014
基于构形理论和(火积)理论, 以当量热阻为目标对层流冷却条件下的圆柱体热源进行构形研究, 分析热源直径和导热系数对其传热性能的影响. 结果表明: 在热源体积一定的条件下, 不存在最佳热源直径使得其当量热阻取得最小值. 随着热源直径的减小、导热系数的增大, 热源当量热阻减小, 此时热源系统的整体传热性能得到提高. 此外, 圆柱体热源表面温度沿来流方向逐渐增大, 且其表面换热系数沿来流方向逐渐减小. 本文所得结果对热源的优化设计有一定的参考价值.
