...Rahim K. Jassim The purpose of this paper is to demonstrate the importance of the use of the exergy analysis in the optimization of the geometry of a periodic-flow regenerator. The optimum geometry of the regenerator is determined using the unit cost of exergy of the warm air delivered...

...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...

It is also shown that the optimal heat exchanger geometry is insensitive to the thermodynamic irreversibility caused by discharging the used ram air into the ambient.

... Enhancement Experimental Geometry Heat Transfer The mechanisms of pool boiling heat transfer have been studied for a long time since it is closely related to the designs of more efficient heat exchangers and heat removal systems. Recently, they have been widely...

...., 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...

...A. Bejan; N. Dan This paper shows that the geometry of the heat flow path between a volume and one point can be optimized in two fundamentally different ways. In the “growth” method of the original constructal theory the structure is optimized starting from the smallest volume element of fixed size...
