Design and Operation of Heat Exchangers and their Networks
Design and Operation of heat Exchangers and their Networks presents a comprehensive and detailed analysis on the thermal design methods for the most common types of heat exchangers, with a focus on their networks, simulation procedures for their operations, and measurement of their thermal performances. Roetzel, Luo and Chen address the fundamental theories and principles of heat transfer performance of heat exchangers and their applications whilst applying them to the use of modern computing technology. The main topics presented in this book include cell method and moving boundary models for condensers and evaporators, dispersion models for heat exchangers, experimental methods for the evaluation of heat exchanger performance, and multi-stream heat exchangers and heat exchanger networks. Includes Matlab and Excel codes to illustrate how the technologies and methods discussed can be easily applied and developed Analyses a range of different models, applications and case studies in order to reveal more advanced solutions for industrial applications Maintains a strong focus on the fundamental theories and principles of the heat transfer performance of heat exchangers and their applications for complex flow arrangement

This work proposes mathematical models and methods for the analytical and numerical treatment of transient processes in single and multi-phase heat exchangers. All important flow arrangements and heat exchanger configurations are considered. The plug-flow, dispersed plug-flow and cell models are applied to describing transient processes in heat exchangers. The Laplace transform and numerical inversion algorithm as well as other methods are used. Numerical examples show the influence of different design parameters on the thermal response to variations of inlet temperatures, flow rates and other operating conditions. This text aims to help enable the designer, manufacturer and user of heat exchangers to understand and predict dynamic behaviour of heat exchangers.

Based on courses for students of science, engineering, and systems science at the Zurich University of Applied Sciences at Winterthur, this text approaches the fundamentals of thermodynamics from the point of view of continuum physics. By describing physical processes in terms of the flow and balance of physical quantities, the author achieves a unified approach to hydraulics, electricity, mechanics and thermodynamics. In this way, it becomes clear that entropy is the fundamental property that is transported in thermal processes (i.e., heat), and that temperature is the corresponding potential. The resulting theory of the creation, flow, and balance of entropy provides the foundation of a dynamical theory of heat. This extensively revised and updated second edition includes new material on dynamical chemical processes, thermoelectricity, and explicit dynamical modeling of thermal and chemical processes. To make the book more useful for courses on thermodynamics and physical chemistry at different levels, coverage of topics is divided into introductory and more advanced and formal treatments. Previous knowledge of thermodynamics is not required, but the reader should be familiar with basic electricity, mechanics, and chemistry and should have some knowledge of elementary calculus. The special feature of the first edition -- the integration of thermodynamics, heat transfer, and chemical processes -- has been maintained and strengthened. Key Features: · First revised edition of a successful text/reference in fourteen years · More than 25 percent new material · Provides a unified approach to thermodynamics and heat transport in fundamental physical and chemical processes · Includes worked examples, questions, and problem sets for use as a teaching text or to test the reader's understanding · Includes many system dynamics models of laboratory experiments
