...K. J. Daun; D. P. Morton; J. R. Howell This paper presents an optimization methodology for designing radiant enclosures containing specularly-reflecting surfaces. The optimization process works by making intelligent perturbations to the enclosure geometry at each design iteration using specialized...

...J. V. C. Vargas and; A. Bejan This paper considers the fundamental problem of optimizing the geometry of the interface between two conductive bodies, with the objective of minimizing the thermal resistance. The interface geometry is free to change. For simplicity, the geometry is assumed to be two...

...., tree networks) have been subjected to the descriptive (not theoretical) technique of fractal geometry. The constructal optimization of paths for internal currents was first proposed in the context of urban growth (Bejan, 1996) and pure heat conduction (Bejan, 1997a, b). In the latter, the channels were...
