This book was released on 2009 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combination of Spectral Methods and Finite Differences will be used to solve the Navier-Stokes equations for a viscous flow past a circular cylinder and past symmetric Joukowski airfoils. Different discretizations of the physical problem will be explored, and the solution of the equations will be analyzed for different geometries and boundary conditions. This project is the continuation of our research started as a Master Thesis at Wichita State University under the advising of Professor Alan Elcrat; the project is a deep exploration of the solution of Navier-Stokes equations by implementing new methods of discretization including spectral differentiation. We will compare results previously obtained by Gauss-Seidel/Successive Over-Relaxation Methods (SOR) together with Finite Differences, with results using Newton's Method, based on work by Bengt Fornberg, but implementing spectral differentiation. As we will see, due to the nature of the physical domain and the conformal map involved to transform it to a more tractable domain, the use of spectral methods in both directions of our two dimensional problem proved to be inefficient due to unnecessary concentration of points in areas of the domain of low gradients. However, to take advantage of spectral methods, we combined spectral methods in one direction with high order finite vii differences on the other direction, where different mesh densities were designed to have higher concentration of points where required. With this discretizations, spectral methods were approached as the limiting order of finite differences as presented in A Practical Guide to Pseudospectral Methods We will explore the solution for flows past more general geometries, symmetric Joukowski airfoils. Then we will study the implementation and effect of suction boundary conditions on the obstacle. In this text I have decided to include part of the introduction and theoretical background shown in my Master thesis to allow new readers to get familiarized with the subject, but the solution scheme, the different discretizations and results are all new explorations that we are proud to present.

Download or read book Numerical Methods for Conservation Laws written by Jan S. Hesthaven and published by SIAM. This book was released on 2018-01-30 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation laws are the mathematical expression of the principles of conservation and provide effective and accurate predictive models of our physical world. Although intense research activity during the last decades has led to substantial advances in the development of powerful computational methods for conservation laws, their solution remains a challenge and many questions are left open; thus it is an active and fruitful area of research. Numerical Methods for Conservation Laws: From Analysis to Algorithms offers the first comprehensive introduction to modern computational methods and their analysis for hyperbolic conservation laws, building on intense research activities for more than four decades of development; discusses classic results on monotone and finite difference/finite volume schemes, but emphasizes the successful development of high-order accurate methods for hyperbolic conservation laws; addresses modern concepts of TVD and entropy stability, strongly stable Runge-Kutta schemes, and limiter-based methods before discussing essentially nonoscillatory schemes, discontinuous Galerkin methods, and spectral methods; explores algorithmic aspects of these methods, emphasizing one- and two-dimensional problems and the development and analysis of an extensive range of methods; includes MATLAB software with which all main methods and computational results in the book can be reproduced; and demonstrates the performance of many methods on a set of benchmark problems to allow direct comparisons. Code and other supplemental material will be available online at publication.

This book was released on 1999 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lectures collected for this volume were given during a workshop entitled, "Semi-analytic Methods for the Navier Stokes Equations" held at the CRM in Montréal. The title reflects the current reality in fluid dynamics: Navier-Stokes equations (NSE) describe the behavior of fluid in a wide range of physical situations, the solutions of these equations are sufficiently complicated, so that another level of analysis is clearly needed. The fundamental problem is not just to solve the NSE, but also to understand what the solutions mean. One of the goals of the workshop was to bring together people who, while working in different fields, share a common perspective on the nature of the problem to be solved. The lectures present a diverse set of techniques for modelling, computing, and understanding phenomena such as instabilities, turbulence and spatiotemporal chaos in fluids.
