Download or read book Thermodiffusion in Multicomponent Mixtures written by Seshasai Srinivasan and published by Springer Science & Business Media. This book was released on 2012-11-13 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermodiffusion in Multicomponent Mixtures presents the computational approaches that are employed in the study of thermodiffusion in various types of mixtures, namely, hydrocarbons, polymers, water-alcohol, molten metals, and so forth. We present a detailed formalism of these methods that are based on non-equilibrium thermodynamics or algebraic correlations or principles of the artificial neural network. The book will serve as single complete reference to understand the theoretical derivations of thermodiffusion models and its application to different types of multi-component mixtures. An exhaustive discussion of these is used to give a complete perspective of the principles and the key factors that govern the thermodiffusion process.

Book Synopsis Theoretical Analysis of Separation of Multicomponent Liquid Mixtures in Thermogravitational Columns and Thermal Diffusion Cells by : Kjetil Braathen Haugen
Download or read book Theoretical Analysis of Separation of Multicomponent Liquid Mixtures in Thermogravitational Columns and Thermal Diffusion Cells written by Kjetil Braathen Haugen and published by . This book was released on 2007 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most naturally occurring fluids are multicomponent mixtures. Nevertheless, measured diffusion coefficients are almost exclusively for binary mixtures. Even for ternary mixtures, data is extremely limited. Molecular diffusion is fundamentally different in multicomponent than in binary mixtures due to cross molecular diffusion. All diffusion coefficients are non-trivial functions of composition, temperature, and pressure. Consequently, ternary diffusion coefficients cannot be obtained from binary data.

Book Synopsis Theoretical and Numerical Investigation of Thermodiffusion (Soret Effect) and Thermosolutal Convection by : Shu Pan
Download or read book Theoretical and Numerical Investigation of Thermodiffusion (Soret Effect) and Thermosolutal Convection written by Shu Pan and published by . This book was released on 2007 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermodiffusion is a mass diffusion phenomenon induced by a temperature gradient and has attracted increasing interests from theorists and experimentalists. In this work, the modelling of thermodiffusion in fluids is theoretically treated in the framework of non-equilibrium thermodynamics. The method developed in this work for thermodiffusion calculation have been incorporated into a computational fluid dynamics program to study the influence of the thermosolutal convection caused by residual gravity and g-jitter. The results have shown that the influence of microgravity environment would become stronger with an increase in the acceleration level, while at the same acceleration level, the effect would decrease at higher frequencies. For an isopropanol-water mixture under a typical microgravity condition for thermodiffusion measurement, the effect of residual gravity lower than 10--5G or the g-jitter components with an acceleration level of 10--4 G and frequencies higher than 0.0005 Hz may be negligible. The analysis in this work has indicated that under the expected microgravity environment on the International Space Station, the influence of g-jitter on the thermodiffusion measurement may be negligibly small for frequencies lower than 1 Hz. Based on four postulates in non-equilibrium thermodynamics, a non-equilibrium thermodynamic approach has been developed for thermodiffusion in associating fluid mixtures. Using the thermodynamic properties provided by the PC-SAFT Equation of State, this approach was used to evaluate the thermal diffusion factor alphaT in aqueous alkanol solutions, including methanol-water, ethanol-water and isopropanol-water mixtures. Using two adjustable parameters calculated from experimental data, the approach has shown a successful estimation of the sign change in the thermodiffusion factor for these mixtures, which was an unresolved problem in thermodiffusion research. In addition to the new model for thermodiffusion in associating mixtures, the current approaches for thermal diffusion estimation in multicomponent hydrocarbon mixtures have been evaluated by comparisons with recent experimental data. Three equations of state, including Peng-Robinson, volume translated Peng-Robinson and PC-SAFT were used in the calculation. The Firoozabadi model combined with vtPR or PC-SAFT was shown to be applicable to thermal diffusion estimation for hydrocarbon mixtures, while PC-SAFT combined with the Firoozabadi model would be a promising choice for mixtures other than hydrocarbons due to the wide applicability of PC-SAFT.
Book Synopsis Multicomponent Diffusion by : E. L. Cussler

Book excerpt: Multicomponent Diffusion discusses the multicomponent diffusion of the three phases of matter. The book is comprised of nine chapters that cover studies of multicomponent diffusion and mass transfer with an emphasis on the chemical characteristics responsible for multicomponent diffusion. Chapter 1 provides an introductory discourse about multicomponent diffusion. Chapter 2 discusses binary diffusion, while Chapter 3 covers multicomponent flux equation. The measurement of ternary diffusion and the estimation of ternary diffusion coefficients are also explained in the book. A chapter then covers the interacting systems, and the subsequent chapter talks about membranes without mobile carriers. The text also discusses carrier-containing membranes and the multicomponent mass transfer. The book will be of great use to researchers and professionals whose work requires a good understanding of multicomponent diffusion.
Book Synopsis Non-equilibrium Thermodynamics For Engineering Applications by : Signe Kjelstrup
Download or read book Non-equilibrium Thermodynamics For Engineering Applications written by Signe Kjelstrup and published by World Scientific. This book was released on 2024-07-23 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the theory of non-equilibrium thermodynamics in a pedagogical and practical way that targets engineering applications. In it, tools to take advantage of the second as well as the first law of thermodynamics are provided.The book starts by explaining how the entropy production is the cornerstone of non-equilibrium thermodynamics — the basis to describe coupled transport phenomena, which are highly relevant for several renewable energy technologies. The book also uses entropy production as the foundation for a systematic methodology to analyze and improve energy efficiency, and shows how entropy production can be used to test the consistency of transport models. The link between transport theory and energy efficiency is also shown, and the relationship to exergy analysis is demonstrated. The theory is applied using examples from practical cases like evaporation, heat exchange, reactor optimization, distillation and more.Non-Equilibrium Thermodynamics for Engineering Applications may be used as a textbook for undergraduate and graduate university curricula containing thermodynamics or energy conversion issues at large, chemical and mechanical engineering, applied chemistry and applied physics.

Book Synopsis Physics of Fluids in Microgravity by : Rodolfo Monti
Download or read book Physics of Fluids in Microgravity written by Rodolfo Monti and published by CRC Press. This book was released on 2002-01-10 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a microgravity experiment, the conditions prevalent in fluid phases can be substantially different from those on the ground and can be exploited to improve different processes. Fluid physics research in microgravity is important for the advancement of all microgravity scients: life, material, and engineering. Space flight provides a unique laboratory that allows scientists to improve their understanding of the behaviour of fluids in low gravity, allowing the investigation of phenomena and processes normally masked by the effects of gravity and thus difficult to study on Earth. Physics of Fluids in Microgravity provides a clear view of recent research and progress in the different fields of fluid research in space. The topics presented include bubles and drops dynamics, Maragoni flows, diffustion and thermodiffusion, solidfication,a nd crystal growth. The results obtained so far are, in some cases, to be confirmed by extensive research activities on the International Space station, where basic and applied microgravity experimentation will take place in the years to come.
