Abstract: Optimization of a fluid distributing tube network plays a critical role in the operation efficiency and energy conservation of a cooling system In this paper, we analyze the effect of multi-dimension on the structure of a fluid distributing tube network for cooling heat-generating, and then seek the optimal fluid structure with minimal pressure drop for a given total volume of the tube network The theoretical results show that the pressure drop of a laminar flow in the tube network reaches the minimum when the cubic value of the parent tube diameter equals to the sum of those of the daughter tube diameter, consistent with Murray's law Furthermore, it is advantageous to have a higher dimension structure in network arrangement when the number of heat generation units increases, ie, network performance improves by adopting a two-dimensional and even three-dimensional format as the number of units grows

Progress in entransy theory and its applications
TL;DR: In this article, the entransy theory and its applications are summarized from several aspects, such as heat conduction, heat convective, heat radiation, heat exchanger design and mass transfer.
"Entransy," and Its Lack of Content in Physics
TL;DR: This paper showed that entransy has no meaning in physics, because, at bottom, it rests on the false claim that in order to transfer heat to a solid body of thermodynamic temperature T, the heat transfer must be proportional to T.

Jianlong Kou,Jianlong Kou,Yanyan Chen,Xiaoyan Zhou,Hangjun Lu,Fengmin Wu,Jintu Fan,Jintu Fan +7 more
TL;DR: In this article, the optimal structures of tree-like branching networks for minimum flow resistance are analyzed for both laminar and turbulent flow in both smooth and rough pipes, and it is found that the dimensionless effective flow resistance under the volume constraint for different flows is sensitive to the geometrical parameters of the structure.
