Workshop: Constructal Theory after 20 Years of Exploration and what the Future Holds?

本次研讨会致力于构造定律，这是一种新的物理理论，源于对自然系统如何随时间演变的思考，以及它对热传递过程的影响。河流流域的形成，哺乳动物肺部的形成，咖啡冲泡的渗透路径，树根和树枝的生长，血管网络的复杂性，所有这些在进化过程中都有相似之处：为了生存，它们似乎必须朝着有利于获取流动物质的结构转变。将构造法领域的热传递过程专家聚集在一起，对于衡量这项新法律迄今在热传递过程中的影响，确定它如何更好地为热传递知识库做出贡献，并确定该领域在不久的将来将如何发展，以指导其传播，至关重要。这也是社区围绕建构法进行组织和规划的机会。对自然系统的观察结果产生的构造定律也可以应用于工程系统，以预测复杂的热传输系统应该如何演变，以便它们继续存在。这个概念本质上与能量和熵平衡的热力学有关，通过需要流动的功（能量）和由此产生的散热。扩散、对流和辐射也与构造定律有着内在的联系，因为它们是影响热系统的最重要的热量和质量传递过程。每种技术在新的热传递过程中的贡献不应仅由材料或制造限制决定，而应考虑到它们将如何促进获得流动。从构造法中诞生的新范式是热设计师不回避几何复杂性；相反，拥抱和探索它，认识到新的形式-功能关系的重要性，以促进对流动的访问。本次研讨会的主要成果预计将是构造法及其对热传输过程的影响的明确方向。

This Workshop is dedicated to the Constructal Law, a new physics theory emanating from the contemplation of how natural systems evolve in time, and its implications to thermal transport processes. The forming of river basins, the shaping of mammal lungs, the percolation paths of coffee brewing, the growth of tree roots and branches, the complexity of blood vessel networks, all have similarities in their evolution: to exist, it seems, they must morph toward structures that facilitate access to what flows. The bringing together of thermal transport processes experts in Constructal Law is paramount to measure the impact so far of this new law in thermal transport processes, to determine how it can better contribute to the thermal transport knowledge base, and to identify how this area will evolve in the near future as to guide its dissemination. It is also an opportunity for the community to organize and plan around constructal law.The observations of natural systems resulting in the constructal law can be applied to engineering systems as well, to anticipate how complex thermal transport systems should evolve so they continue to exist. This concept is intrinsically related to the Thermodynamics of energy and entropy balances, via the work (energy) needed to flow and the dissipating heat resulting from it. Diffusion, convection, and radiation are also intrinsically related to constructal law, as they are the most important heat and mass transport processes affecting thermal systems. The contributions of each in new thermal transport processes should not be dictated by materials or manufacturing limitations alone, but should also account for how they will contribute to facilitating access to what flows. The new paradigm born out of constructal law is for the thermal designer not to avoid geometric complexity; rather, to embrace and explore it, to recognize the importance of new form-function relationships as to facilitate access to what flows. The main outcome of this workshop is expected to be a clear direction of constructal law and its implications to thermal transport processes.
