Non-equilibrium thermodynamics of heterogeneous systems by Signe Kjelstrup( )

25 editions published in 2008 in English and held by 1,721 WorldCat member libraries worldwide

"The purpose of this book is to encourage the use of non-equilibrium thermodynamics to describe transport in complex, heterogeneous media. With large coupling effects between the transport of heat, mass, charge and chemical reactions at surfaces, it is important to know how one should properly integrate across systems where different phases are in contact. No other book gives a prescription of how to set up flux equations for transports across heterogeneous systems." "The authors apply the thermodynamic description in terms of excess densities, developed by Gibbs for equilibrium, to non-equilibrium systems. The treatment is restricted to transport into and through the surface. Using local equilibrium together with the balance equations for the surface, expressions for the excess entropy production of the surface and of the contact line are derived. Many examples are given to illustrate how the theory can be applied to coupled transport of mass, heat, charge and chemical reactions; in phase transitions, at electrode surfaces and in fuel cells. Molecular simulations and analytical studies are used to add insight."--Jacket
The collected works of Lars Onsager : with commentary by Lars Onsager( )

16 editions published between 1996 and 1998 in English and held by 854 WorldCat member libraries worldwide

This volume contains the collected works of the eminent chemist and physicist Lars Onsager, one of the most influential scientists of the 20th century. The volume includes Onsager's previously unpublished PhD thesis, a biography by H.C. Longuet-Higgins and M.E. Fisher, an autobiographical commentary, selected photographs, and a list of Onsager discussion remarks in print. Onsager's scientific achievements were characterized by deep insights into the natural sciences. His two best-known accomplishments are his reciprocal relations for irreversible processes, for which he received the 1968 Nobel Prize in Chemistry, and his explicit solution of the two-dimensional Ising model, a mathematical tour de force that created a sensation when it appeared. In addition, he made significant theoretical contributions to other fields, including electrolytes, colloids, superconductivity, turbulence, ice, electrons in metals, and dielectrics. In this volume, Onsager's contributions are divided into the following fields: irreversible processes; the Ising model; electrolytes; colloids; helium II and vortex quantization; off-diagonal long-range order and flux quantization; electrons in metal; turbulence; ion recombination; fluctuation theory; dielectrics; ice and water; biology; Mathieu functions. The different fields are evaluated by leading experts. The commentators are P.W. Anderson, R. Askey, A. Chorin, C. Domb, R.J. Donnelly, W. Ebeling, J-C Justice, H.N.W. Lekkerkerker, P. Mazur, H.P.

Non-equilibrium thermodynamics with applications by Dick Bedeaux( )

12 editions published between 2015 and 2016 in English and held by 580 WorldCat member libraries worldwide

The book covers recent developments in the theory of non-equilibrium thermodynamics and its applications. Four chapters are devoted to the foundations; an overview chapter is followed by recent results addressing the underlying principles of the theory. The applications are concerned with bulk systems, with heterogeneous systems where interfaces are central and with process units in industry where entropy production minimization is useful. There is also a collection of chapters under the heading mesoscopic non-equilibrium thermodynamics, giving in the end an overview of extensions of the theory into the non-linear regime. Bringing the literature up to date and detailing new approaches in this area of research, it is aimed at a predominantly, but not exclusively, academic audience of practitioners of thermodynamics and energy conversion

Non-equilibrium thermodynamics for engineers by Signe Kjelstrup( Book )

16 editions published between 2010 and 2017 in English and held by 137 WorldCat member libraries worldwide

The book describes in a simple and practical way what non-equilibrium thermodynamics is and how it can add to engineering fields. It explains how to describe proper equations of transport, more precise than used so far, and how to use them to understand the waste of energy resources in central unit processes in the industry. It introduces the entropy balance as an additional equation to use, to create consistent thermodynamic models, and a systematic method for minimizing energy losses that are connected with transport of heat, mass, charge, momentum and chemical reactions. --Book Jacket

Seebeck coefficients of cells with molten carbonates relevant for the metallurgical industry( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: We report Seebeck coefficients of electrochemical cells with molten carbonate mixtures as electrolytes and carbon dioxide|oxygen electrodes. The system is relevant for use of waste heat and off-gases with concentration of carbon dioxide different from air, as for example in the metallurgical industry. The coefficient is −1.25 mV K −1 for a nearly equimolar mixture of lithium and sodium carbonate with dispersed magnesium oxide at 750 °C, one bar total pressure and a pressure ratio of carbon dioxide to oxygen of 2:1. The value is slightly lower when sodium is replaced by potassium. The theoretical expression of the Seebeck coefficient was established using the theory of non-equilibrium thermodynamics. We used this expression to predict an increase to −1.4 mV K −1 when lowering the gas partial pressures to 0.015 and 0.2 bar, respectively, for carbon dioxide and oxygen, a gas composition that can represent that of the off-gases from a silicon furnace which we are concerned with. The absolute value of the Seebeck coefficient increases by 0.2 mV K −1 when the cell average temperature increases from 550 to 850 °C. The presence of a second component in the electrolyte increases the coefficient significantly above the values obtained with one component, compatible with a lowering of the transported entropy of the carbonate ion. A concentration cell, using the off-gas from the silicon furnace as anode gas and air as cathode gas, will add 0.14 V at 550°C to the absolute value of the potential. The series construction has the potential to offer a power density at matched load conditions in the order of 0.5 kW m −2
