This book was released on 2014-05-10 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Solutions of Boundary Value Problems for Ordinary Differential Equations covers the proceedings of the 1974 Symposium by the same title, held at the University of Maryland, Baltimore Country Campus. This symposium aims to bring together a number of numerical analysis involved in research in both theoretical and practical aspects of this field. This text is organized into three parts encompassing 15 chapters. Part I reviews the initial and boundary value problems. Part II explores a large number of important results of both theoretical and practical nature of the field, including discussions of the smooth and local interpolant with small K-th derivative, the occurrence and solution of boundary value reaction systems, the posteriori error estimates, and boundary problem solvers for first order systems based on deferred corrections. Part III highlights the practical applications of the boundary value problems, specifically a high-order finite-difference method for the solution of two-point boundary-value problems on a uniform mesh. This book will prove useful to mathematicians, engineers, and physicists.

This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IMA Volume in Mathematics and its Applications COMPUTATIONAL FLUID DYNAMICS AND REACTING GAS FLOWS is in part the proceedings of a workshop which was an integral part of the 1986-87 IMA program on SCIENTIFIC COMPUTATION. We are grateful to the Scientific Committee: Bjorn Engquist (Chairman), Roland Glowinski, Mitchell Luskin and Andrew Majda for planning and implementing an exciting and stimulating year-long program. We especially thank the Workshop Organizers, Bjorn Engquist, Mitchell Luskin and Andrew Majda, for organizing a workshop which brought together many of the leading researchers in the area of computational fluid dynamics. George R. Sell Hans Weinberger PREFACE Computational fluid dynamics has always been of central importance in scientific computing. It is also a field which clearly displays the essential theme of interaction between mathematics, physics, and computer science. Therefore, it was natural for the first workshop of the 1986- 87 program on scientific computing at the Institute for Mathematics and Its Applications to concentrate on computational fluid dynamics. In the workshop, more traditional fields were mixed with fields of emerging importance such as reacting gas flows and non-Newtonian flows. The workshop was marked by a high level of interaction and discussion among researchers representing varied "schools of thought" and countries.

This book was released on 2018-06-28 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The numerical solution of exterior problems is typically accomplished by introducing an artificial, far field boundary and solving the equations on a truncated domain. For hyperbolic systems, boundary conditions at this boundary are often derived by imposing a principle of no reflection. However, waves with spherical symmetry in gas dynamics satisfy equations where incoming and outgoing Riemann variables are coupled. This suggests that natural reflections may be important. A reflecting boundary condition is proposed based on an asymptotic solution of the far field equations. Nonlinear energy estimates are obtained for the truncated problem and numerical experiments presented to validate the theory. Hagstrom, Thomas and Hariharan, S. I.

This book was released on 1982 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a finite difference technique for solving problems in nonsteady, two-dimensional, inviscid flow of an ideal gas. The technique solves the equations of gas dynamics in transformed coordinates obtained by conformal mapping of the physical domain of the problem. Irregular physical domains with curved or piecewise-straight boundaries are transformed onto rectangles to facilitate the application of boundary conditions in the finite difference calculations. The differential equations fo fluid flow in conservation law form are solved by means of either the two-step Lax-Wendroff of MacCormack's finite difference method. An expedient means of obtaining coordinate transformations by a numerical integration of a Schwartz-Christoffel type differential equation has been used for problems in transient external aerodynamics. An extensive series of test problems, consisting of one-dimensional traveling shock waves, two-dimensional steady Prandtl-Meyer expansions, and oblique shocks were solved so that the finite difference calculations could be compared with exact mathematical results. Nonsteady Mach reflections were computed and compared with approximate theory and experimental data to test the technique for problems that are both fully two-dimensional and nonsteady.
