Elementary Heat Transfer Analysis provides information pertinent to the fundamental aspects of the nature of transient heat conduction. This book presents a thorough understanding of the thermal energy equation and its application to boundary layer flows and confined and unconfined turbulent flows. Organized into nine chapters, this book begins with an overview of the use of heat transfer coefficients in formulating the flux condition at phase interface. This text then explains the specification as well as application of flux boundary conditions. Other chapters consider a derivation of the transient heat conduction equation. This book discusses as well the convective energy transport based on the understanding and application of the thermal energy equation. The final chapter deals with the study of the processes of heat transfer during boiling and condensation. This book is a valuable resource for Junior or Senior engineering students who are in an introductory course in heat transfer.

Radiant Energy Spectrum Converters For Solar Energy Harvesting written by Nima Talebzadeh Gargari and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2021 with categories.

Solar energy is a particularly attractive form of renewable energy because it is widely available and the amount of solar energy received on Earth each year is ~3.5 x 10^6 EJ, which is more than 7000 times greater than the annual global energy consumption. However, solar energy remains largely untapped because it is a broadband, intermittent and sparse resource, making it difficult to harness. Herein, the implementation of newly designed optical cavities, referred to as Radiant Energy Spectrum Convertors (RESC), in the form of ellipsoids, spheroids and/or paraboloids is presented for broadband solar energy harvesting and conversion applications. In this thesis RESC structures are designed and their application in four broadband solar energy harvesting applications is numerically analyzed: 1) photobioreactors, 2) agri-voltaics, 3) hybrid solar lighting, and 4) Solar Thermophotovoltaics (STPV). 1) The RESC structure in the photobioreactor is a luminescent solar spectrum splitter that partitions the solar irradiance into photosynthetically active radiation (PAR) and photosynthetically inactive radiation (non-PAR) to simultaneously power algae cultivation systems and PV cells, respectively. Results show that a RESC structure enables 0.25 MJ of electric power generation in a photobioreactor with a projected area of and volume of 0.2 m^2 and 0.2 m^3, respectively. 2) The RESC structure implemented in agri-voltaics is an elliptic array luminescent solar concentrator for combined power generation and microalgae growth with the similar concept of partitioning solar irradiance into its PAR and non-PAR components. Considering the combined effects of emission, transmission and surface scattering losses, numerical results show the optical efficiency of the elliptic array luminescent solar concentrator (LSC) is 63%, whereas in comparison the optical efficiency for a conventional planar LSC of the same size is 47.2%. 3) The RESC structures used in hybrid solar lighting applications are based on luminescent solar spectrum splitters that partition the incoming solar irradiance into its visible and non-visible components to simultaneously power fibre optic lighting system and PV cells, respectively. Numerical analysis shows that the non-visible portion of the solar irradiance can be converted to electricity with an efficiency of 13.4% using a double-junction PV cell within a RESC structure. 4) RESC structures implemented into STPV systems are based on highly specular IR reflective optical cavities in the form of oblate and prolate spheroid structures to enhance the power density and photoconversion efficiency of the STPV systems. The optical cavity partially encloses a solar receiver that is located at the focal point of an ellipsoid/paraboloid. Concentrated solar radiation is absorbed by the receiver, which functions as both an absorber and an emitter. Radiation is emitted from the emitter, and the internal surface of the cavity is able to reflect a large portion of this emitted radiation either back to the emitter or to a PV cell. Emitted radiation that is returned to the emitter is referred to as "photon recycling". A high degree of photon recycling can be used to achieve high emitter temperatures, which enhances the performance of STPV systems. The results presented in this thesis show that optical structures in the form of spheroids and paraboloids can be used to partition, control and harness broadband solar energy to simultaneously provide for multiple applications, which ultimately increases overall solar energy conversion efficiencies.

This book offers a complete guide to designing Linear Fresnel Reflector Systems for concentrating solar radiation. It includes theoretical analyses, computational tools and mathematical formulae to facilitate the development, design, construction and application of these systems. In addition, the book presents a concise yet thorough treatment of the theory behind these systems, and provides useful and efficient calculation procedures that can be used to model and develop their practical applications. Along with the theoretical analyses provided in the book, the physical background is explained using mathematical formulae, illustrations, graphs and tables. Methods are presented for solving the non-linear mathematical systems that describe a significant variety of cases. In addition, MATLAB codes are supplied (both in the text and online). Consequently, readers interested in applying the methodology presented here will have all the source codes at hand, allowing them to easily expand on them by introducing appropriate modifications for their respective design configuration. Given its scope, the book will be of interest to engineers and researchers, who can use their scientific background to help them develop more energy-efficient Linear Fresnel Reflector systems. It will also appeal to students studying these systems for the first time, as it supplies a comprehensive overview of their theoretical analysis and applications.

This handbook aims at providing a comprehensive resource on solar energy. Primarily intended to serve as a reference for scientists, students and professionals, the book, in parts, can also serve as a text for undergraduate and graduate course work on solar energy. The book begins with availability, importance and applications of solar energy, definition of sun and earth angles and classification of solar energy as thermal and photon energy. It then goes onto cover day lighting parameters, laws of thermodynamics including energy and exergy analysis, photovoltaic modules and materials, PVT collectors, and applications such as solar drying and distillation. Energy conservation by solar energy and energy matrices based on overall thermal and electrical performance of hybrid system are also discussed. Techno-economic feasibility of any energy source is the backbone of its success and hence economic analysis is covered. Some important constants, such as exercises and problems increase the utility of the book as a text.
