Climate change, in the framework of the constructal law
Clausse, M.; Meunier, F.; Reis, A. H.; Bejan, A.Here we present a simple and transparent model of thermal behavior under time-changing conditions. We show the one-to-one relationship between changes in atmospheric properties and time-dependent changes in temperature and its distribution on Earth. The model accounts for convection and radiation, thermal inertia and changes in albedo () and greenhouse factor (). The constructal law is used as the principle ...
Using the constructal law to predict climate changes versus atmospheric properties
Meunier, F.; clausse, M.; Reis, A. Heitor; Bejan, A.A simple and transparent model, based on the constructal law, is used to study climate change as a response to changes in atmospheric properties (albedo-- and greenhouse factor –-). This model is first used to study the climate response to present changes in albedo and greenhouse factor. This allows comparing, in terms of energy imbalance and temperature, the climate change observed between 1880 and 2003 and ...
Along with Constructal Theory
Bejan, A; Lorente, S.; Miguel, A. F.; Reis, A.The Constructal Theory proposed by Adrian Bejan in 1996 is a deterministic principle for self-organization and self-optimization of natural systems. Its quantitative and holistic approach, which builds and ensemble from small, diverse building blocks, mirrors the logic of growing of natural systems. This is the first book of a new series devoted to workshops of FGE of the UNIL.
Constructal theory of global circulation and climate
Reis, A. Heitor; Bejan, AThe constructal law states that every flow system evolves in time so that it develops the flow architecture that maximizes flow access under the constraints posed to the flow. Earlier applications of the constructal law recommended it as a self-standing law that is distinct from the second law of thermodynamics. In this paper, we develop a model of heat transport on the earth surface that accounts for the solar...
Thermodynamic optimization of global circulation and climate
Bejan, A.; Reis, A. HeitorThe constructal law of generation of flow structure is used to predict the main features of global circulation and climate. The flow structure is the atmospheric and oceanic circulation. This feature is modelled as convection loops, and added to the earth model as a heat engine heated by the Sun and cooled by the background. It is shown that the dissipation of the power produced by the earth engine can be maxim...
Porous and Complex Flow Structures in Modern Technologies
Bejan, A.; Dincer, I; Lorente, S; Miguel, A. F.; Reis, A. H.Porous and Complex Flow Structures in Modern Technologies represents a new approach to the field, considering the fundamentals of porous media in terms of the key roles played by these materials in modern technology. Intended as a text for advanced undergraduates and as a reference for practicing engineers, the book uses the physics of flows in porous materials to tie together a wide variety of important issues...
