Bejan s constructal theory is explored for a paradigm problem in electrical theory, analogue of a wide range of transport problems involving flow subject to a Ohm s Law model. The equi-potential optimisation is derived and generalised to further functional behaviour of resistances. The original case illustrates the power of Bejan s asymptoticintersection method. 2002 Elsevier Science Ltd. All r...

In this paper we propose a constructal approach to understanding and predicting the morphology of agglomerates of aerosol particles and also to the design of air-cleaning devices. We show that particle agglomeration begins in spherical shape and switches to needle-shaped agglomeration, which performs best as a particle collector at long times. The shape of the needle depends on the dipolar mome...

The effectiveness of microchannels in enhancing heat transfer has been demonstrated in the semiconductor industry. In order to tap the microscale heat transfer effects into macro geometries, overcoming the cost and technological constraints, microscale passages were created in macro geometries machined using conventional fabrication methods. A cylindrical insert was placed within a pipe, and ge...
