Shape from function: The exergy cost of viscous flow in bifurcated diabatic tubes

Abstract

Bifurcated flows are ubiquitous in nature. Their being such a common feature of many natural “structures” has prompted a multitude of investigations in diverse scientific branches: botanists, neurophysicians, biologists and chemists have attempted to find a “structural plan” on which to build a general model of the formation and evolution of bifurcations. Not incidentally, the engineering side of the issue is also extremely interesting: from heat exchangers to pipelines to district heating networks, the existence of a “general geometric model” would much facilitate a designer’s life.
