Available in PDF, EPUB and Kindle. Book excerpt: A mathematical model of the entire furrow-irrigation process has been developed. This model can be used to analyze and predict the performance of free-draining sloping furrow irrigation systems; capability for preduction of low with cutback was also provided. The model is based on the solution of the complete continuity and momentum conservation equations, which govern the unsteady, gradually varied flow of water in open channels. Therefore, it is a complete hydrodynamic model. In addition, it has been demonstrated that zero-inertia conditions can also be simulated by the present model. A fully implicit finite-difference scheme was used to find approximate solutions for the integrated form of the non-linear governing equations, which are simultaneously solvedby the double-sweep technique. The input to the model consists of the inflow discharge, furrow slape, cutoff (application) time, lenght, roughness (the Manning n), soil-infiltration characteristics (k and a in the Kostiaskov equation), and furrow shape (C and M in the top width equation, B = Cym, for a power-law cross section0. output information consists of advance and recession times, post-irrigation areal distribution of infiltrated water along the furrow, runoff volume, as well as water application and storage efficiencies. Dimensional analysis was applied to reduce the number of governing parameters in the equations. Model performance was evaluated by comparison with field data. The results of both the hydrodynamic and the zero-inertia approaches ...

This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 1994 Professor Enok Palm celebrated his 70th birthday and retired after more than forty years of service at the University of Oslo. In view of his outstanding achievements as teacher and scientist a symposium entitled "Waves and Nonlinear Processes in Hydrodynamics" was held in his honour from the 17th to the 19th November 1994 in the locations of The Norwegian Academy of Science and Letters in Oslo. The topics of the symposium were chosen to cover Enok's broad range of scientific work, interests and accomplishments: Marine hydrodynamics, nonlinear wave theory, nonlinear stability, thermal convection and geophys ical fluid dynamics, starting with Enok's present activity, ending with the field where he began his career. This order was followed in the symposium program. The symposium had two opening lectures. The first looked back on the history of hydrodynamic research at the University of Oslo. The second focused on applications of hydrodynamics in the offshore industry today.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a hierarchy of macroscopic models for semiconductor devices, studying three classes of models in detail: isentropic drift-diffusion equations, energy-transport models, and quantum hydrodynamic equations. The derivation of each, including physical discussions, is shown. Numerical simulations for modern semiconductor devices are performed, showing the particular features of each. The author develops modern analytical techniques, such as positive solution methods, local energy methods for free-boundary problems and entropy methods.

Download or read book Numerical Modelling of Wave Energy Converters written by Matt Folley and published by Academic Press. This book was released on 2016-06-14 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Modelling of Wave Energy Converters: State-of-the Art Techniques for Single WEC and Converter Arrays presents all the information and techniques required for the numerical modelling of a wave energy converter together with a comparative review of the different available techniques. The authors provide clear details on the subject and guidance on its use for WEC design, covering topics such as boundary element methods, frequency domain models, spectral domain models, time domain models, non linear potential flow models, CFD models, semi analytical models, phase resolving wave propagation models, phase averaging wave propagation models, parametric design and control optimization, mean annual energy yield, hydrodynamic loads assessment, and environmental impact assessment. Each chapter starts by defining the fundamental principles underlying the numerical modelling technique and finishes with a discussion of the technique’s limitations and a summary of the main points in the chapter. The contents of the chapters are not limited to a description of the mathematics, but also include details and discussion of the current available tools, examples available in the literature, and verification, validation, and computational requirements. In this way, the key points of each modelling technique can be identified without having to get deeply involved in the mathematical representation that is at the core of each chapter. The book is separated into four parts. The first two parts deal with modelling single wave energy converters; the third part considers the modelling of arrays; and the final part looks at the application of the different modelling techniques to the four most common uses of numerical models. It is ideal for graduate engineers and scientists interested in numerical modelling of wave energy converters, and decision-makers who must review different modelling techniques and assess their suitability and output. Consolidates in one volume information and techniques for the numerical modelling of wave energy converters and converter arrays, which has, up until now, been spread around multiple academic journals and conference proceedings making it difficult to access Presents a comparative review of the different numerical modelling techniques applied to wave energy converters, discussing their limitations, current available tools, examples, and verification, validation, and computational requirements Includes practical examples and simulations available for download at the book’s companion website Identifies key points of each modelling technique without getting deeply involved in the mathematical representation
