摘要: Abstract This paper is an introduction to a new trend in the conceptual design of energy systems: generation flow configuration based on “constructal” principle that global performance maximized by balancing and arranging various resistances (the irreversibilities) system free morph. The focuses distribution collection, which are flows connect one point (source, or sink) with infinity points (volume, area, curve). configurations emerge from this tree-shaped, systems employ them “vascularized”. traces most recent progress made constructal vascularization. direction large-scale applications toward microscales. tree-shaped designs electric power networks for natural gas water now invading small-scale such as fuel cells, heat exchangers cooled packages electronics. These have several properties common: freedom morph, multiple scales, hierarchy, nonuniform (optimal) scales through available volume, compactness finite complexity.
