Constructal Design of High-Conductivity Inserts
Bejan presented the Constructal Theory by solving an optimization problem for the cooling of a heat generating volume . The proposed problem was “how to collect and channel to one point the heat generated volumetrically in a low conductivity volume of given size.” The proposed approach defined an elemental construct for which the geometry was optimized. The elemental construct had rectangular shape and consisted of two regions: one region with a low-conductivity material and heat generation and a second region with high-conductivity material that was used to conduct the generated heat to the exterior through one end (Fig. 6.1a). The fraction of high-conductivity material was fixed. More complex forms (assemblies) were obtained by combining the optimized elemental form as shown in Fig. 6.1b–d.
