Design with Constructal Theory 论文

摘要

Constructal theory is the view that the generation of “designedness ” in nature is a universal (physics) phenomenon that can be based on principle (the constructal law): “For a finite-size flow system to persist in time (to live) its configuration must change in time so that it provides greater and greater access to its currents”. This principle predicts natural form across the board, from river basins to animal design, engineering and social dynamics. In this introduction to the theory we show examples of vascular designs at large and small scales and multi-objective flow configurations. 1. The constructal law of generation of flow configuration In this review we draw attention to a new book [1] in which we used constructal theory to design strategies for more effective flow and transport. Constructal theory is the view that the generation of flow configuration in a universal phenomenon of all physics, which is covered by a principle (the constructal law): “For a finite-size flow system to persist in time (to live) it must evolve such that it provides greater and greater access to the currents that flow through it ” [2, 3].
