Available in PDF, EPUB and Kindle. Book excerpt: A method of entropy analysis according to the second law of thermodynamics is proposed for the assessment of a class of practical non-equilibrium two-phase flow models. Entropy conditions are derived directly from a local instantaneous formulation for an arbitrary control volume of a structural two-phase fluid, which are finally expressed in terms of the averaged thermodynamic independent variables and their time derivatives as well as the boundary conditions for the volume. On the basis of a widely used thermal-hydraulic system code it is demonstrated with practical examples that entropy production rates in control volumes can be numerically quantified by using the data from the output data files. Entropy analysis using the proposed method is useful in identifying some potential problems in two-phase flow models and predictions as well as in studying the effects of some free parameters in closure relationships.

Book excerpt: The Second Law, a cornerstone of thermodynamics, governs the average direction of dissipative, non-equilibrium processes. But it says nothing about their actual rates or the probability of fluctuations about the average. This interdisciplinary book, written and peer-reviewed by international experts, presents recent advances in the search for new non-equilibrium principles beyond the Second Law, and their applications to a wide range of systems across physics, chemistry and biology. Beyond The Second Law brings together traditionally isolated areas of non-equilibrium research and highlights potentially fruitful connections between them, with entropy production playing the unifying role. Key theoretical concepts include the Maximum Entropy Production principle, the Fluctuation Theorem, and the Maximum Entropy method of statistical inference. Applications of these principles are illustrated in such diverse fields as climatology, cosmology, crystal growth morphology, Earth system science, environmental physics, evolutionary biology and technology, fluid turbulence, microbial biogeochemistry, plasma physics, and radiative transport, using a wide variety of analytical and experimental techniques. Beyond The Second Law will appeal to students and researchers wishing to gain an understanding of entropy production and its central place in the science of non-equilibrium systems – both in detail and in terms of the bigger picture.

This book was released on 2001-11-30 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of deriving irreversible thermodynamics from the re versible microscopic dynamics has been on the agenda of theoreti cal physics for a century and has produced more papers than can be digested by any single scientist. Why add to this too long list with yet another work? The goal is definitely not to give a gen eral review of previous work in this field. My ambition is rather to present an approach differing in some key aspects from the stan dard treatments, and to develop it as far as possible using rather simple mathematical tools (mainly inequalities of various kinds). However, in the course of this work I have used a large number of results and ideas from the existing literature, and the reference list contains contributions from many different lines of research. As a consequence the reader may find the arguments a bit difficult to follow without some previous exposure to this set of problems.

Available in PDF, EPUB and Kindle. Book excerpt: The standard contemporary approaches to modelling non-equilibrium, many-body phenomena are to use detailed computational models or to analyse large datasets. Here we explore an alternative approach: the use of simple idealized models based on the novel application of statistical mechanics in a non-equilibrium, many-body setting. This thesis has two main elements. The first element is the development of idealized statistical mechanics models to address particular topics in physics and biology. The particular topics to be addressed are as follows: (i) we show using a statistical mechanics approach that global patterns of tree/grass co-existence in savanna ecology can be interpreted as primarily the result of the different water use of trees and grasses subject to considerable fluctuation due to other factors such as disturbances; (ii) we discuss the unification of stochastic and mechanistic approaches in community ecology using a statistical mechanics framework, and develop a statistical mechanical model of a plant ecosystem to predict species abundance patterns, stability-diversity relationships and a phase transition between vegetated and non-vegetated community states, aspects of ecosystem behaviour which have so far been studied largely in isolation from one another; (iii) we clarify aspects of Malkus's variational approach to anisotropic, inhomogeneous fluid turbulence and revisit his statistical stability argument for maximising flow quantities, discussing possible connections to statistical mechanical justifications for flow quantity maximisation. The second main element of this thesis is the discussion of some of the broader methodological concerns surrounding the use of statistical mechanics in a generalised non-equilibrium setting. A central theme of this discussion is emphasizing the distinction between statistical mechanics and statistical inference.
