Abstract
This paper suggests a new engineering design methodology by utilizing the optimality of branching network in nature, such as botanical tree and root systems, animal vascular systems, and so on. The growth mechanism of branching networks in nature is studied and the generation process is reproduced. By applying the generation method of the branching network, a branch-like cooling pipe system is constructed inside a plate with a certain heat flux distributed on its upper surface. Finite element analysis of temperature distribution is implemented, and the cooling performances of such cooling systems are discussed. The effectiveness of the generation method is also confirmed by comparing the result with that from conventional design method.
