Download or read book Numerical Simulation of the Gravity Inertial Spreading of Oil Using Smoothed Particle Hydrodynamics written by Carlos Alberto Dutra Fraga Filho and published by Cambridge Scholars Publishing. This book was released on 2024-09-05 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil spills at sea are a severe environmental concern. They can occur during the various stages of well-drilling, repair operations or transportation. The spreading of oil occurs due to the pollutant's tendency to flow over itself. Knowledge of its physical properties during the phenomenon, such as velocities and spatial positions, allows the timely adoption of environmental protection measures. This book presents, in a simple and objective way, the development and implementation of purely Lagrangian numerical modelling using the Smoothed Particle Hydrodynamics (SPH) method for the study of the spreading of oil in its first stage (gravity-inertial regime) on a calm sea. The computational code's implementation and validation were carried out through the simulation of classical problems in the scientific literature, i.e., heat diffusion in a homogeneous flat plate, a still volume of water inside an immobile reservoir and a dam failure. From the coupling of the software with a collision detection and response algorithm, numerical results in concordance with the curve adjusted by James Fay (a pioneering scientist in the study of oil spills) for the prediction of oil slick diameters at the end of the gravity-inertial regime were achieved.

An appendix at the end of the book provides an introduction to the essentials of the finite element method, and suggests a short list of texts on the subject which are categorized by their level of mathematics.

Download or read book Smoothed Particle Hydrodynamics written by Carlos Alberto Dutra Fraga Filho and published by Springer. This book was released on 2018-11-30 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on results obtained over a decade of study and research. It questions the use of dynamic molecular models in the continuum scale providing alternative solutions to open problems in the literature. It provides a physical-mathematical understanding of the differential equations that govern fluid flow and energy transport, serving as a reference to the application of Smoothed Particle Hydrodynamics in continuum fluid mechanics and transport phenomena. The physical-mathematical modelling of the problems in the continuum scale and the employment of the SPH method for solving the equations are presented. Examples of applications in continuum fluid mechanics with numerical results and discussions are also provided. This literature defends the concepts of continuum mechanics and the application of boundary treatment techniques that do not violate the laws of physics.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of human-caused global warming are obvious, requiring new strategies and approaches. The concept of business-as-usual is now no longer beneficial. Extraction of renewable energy in marine environments represents a viable solution and an important path for the future. These huge renewable energy resources in seas and oceans can be harvested, including wind, tide, and waves. Despite the initial difficulties related mostly to the elevated operational risks in the harsh marine environment, newly developed technologies are economically effective or promising. Simultaneously, many challenges remain to be faced. These are the main issues targeted by the present book, which is associated with the Special Issue of Energies Journal entitled “Renewable Energy in Marine Environment”. Papers on innovative technical developments, reviews, case studies, and analytics, as well as assessments, and papers from different disciplines that are relevant to the topic are included. From this perspective, we hope that the results presented are of interest to for scientists and those in related fields such as energy and marine environments, as well as for a wider audience.

Download or read book Computational Fluid Dynamics written by Adela Ionescu and published by BoD – Books on Demand. This book was released on 2018-02-14 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a careful selection of contributors in the field of CFD. It is divided into three sections according to the purpose and approaches used in the development of the contributions. The first section describes the "high-performance computing" (HPC) tools and their impact on CFD modeling. The second section is dedicated to "CFD models for local and large-scale industrial phenomena." Two types of approaches are basically contained here: one concerns the adaptation from global to local scale, - e.g., the applications of CFD to study the climate changes and the adaptations to local scale. The second approach, very challenging, is the multiscale analysis. The third section is devoted to "CFD in numerical modeling approach for experimental cases." Its chapters emphasize on the numerical approach of the mathematical models associated to few experimental (industrial) cases. Here, the impact and the importance of the mathematical modeling in CFD are focused on. It is expected that the collection of these chapters will enrich the state of the art in the CFD domain and its applications in a lot of fields. This collection proves that CFD is a highly interdisciplinary research area, which lies at the interface of physics, engineering, applied mathematics, and computer science.
