Constructal study on optimizing the pressure drop of the flow channel configurations with two diameters

형상법칙을 이용한 트리구조의 압력강하 최적화 연구

An analytical study was carried out on the flow resistance of tree-shaped channel flow architectures, based on the principle of the constructal law of evolutionary increase of flow access through the generation of better flowing configurations with two diameters in the square domain. Two types of tree-shaped configurations are optimized. The minimized global flow resistance decreases definitely as the system size, N, increases. And the best channel configurations among the first construct and second construct as a result of regarding pressure drop was selected. We also show that the freedom to morph the design and to increase its performance can be enhanced by using tree-tree configurations with $2^{nd}$ construct when N is greater than 18.
