A Numerical Technique for Solution of Multidimension Hydrodynamic Problems
Author: R. Bjork
Publisher:
ISBN:
Category : Hydrodynamics
Languages : en
Pages : 132
Book Description
This Memorandum discusses in detail a numerical method for solving the compressible, hydrodynamic equations under the limitations of (1) two space dimensions, (2) the inviscid approximation, and (3) the adiabatic approximation. The method allows for the occurrence of shocks, contact discontinuities, and interfaces. Under a proper prescription of initial and boundary conditions, the method generates solutions including the above physical phenomena. The basis of the method is the extension to two space dimensions of the particle-in-cell (PIC) concept first proposed by Harlow for a one-dimensional computational scheme. The computational method approximates a set of partial differential equations containing terms in addition to those of the compressible, hydrodynamic equations under the approximations cited. The computational scheme contains a feature known as grid-changing, which permits optimum resolution of all phases of the problem using the limited memory capacity of present day electronic computers.

ISBN:
Category : Breeder reactors
Languages : en
Pages : 108
Book Description
The results are presented of Phase 1 of the APRICOT (Analysis of PRImary COntainment Transients) Program. APRICOT is an international cooperative activity for comparison and benchmarking of computational methods used to analyze LMFBR structural response to pressure loads from CDA's (Core Disruptive Accidents). Phase 1 involved parallel calculations of three computer problems by scientific groups in Europe, Japan and the United States. Independent experts reviewed these calculations for the purpose of comparing computational results and methods of solution. The main conclusion was that all calculations were in reasonable agreement, although there were some basic differences in details and approach to solution of the problems.

Numerical Modeling of Explosives and Propellants
Author: Charles L. Mader
Publisher: CRC Press
ISBN: 142005239X
Category : Technology & Engineering
Languages : en
Pages : 539
Book Description
Major advances, both in modeling methods and in the computing power required to make those methods viable, have led to major breakthroughs in our ability to model the performance and vulnerability of explosives and propellants. In addition, the development of proton radiography during the last decade has provided researchers with a major new experimental tool for studying explosive and shock wave physics. Problems that were once considered intractable – such as the generation of water cavities, jets, and stems by explosives and projectiles – have now been solved. Numerical Modeling of Explosives and Propellants, Third Edition provides a complete overview of this rapidly emerging field, covering basic reactive fluid dynamics as well as the latest and most complex methods and findings. It also describes and evaluates Russian contributions to the experimental explosive physics database, which only recently have become available. This book comes with downloadable resources that contain— · FORTRAN and executable computer codes that operate under Microsoft® Windows Vista operating system and the OS X operating system for Apple computers · Windows Vista and MAC compatible movies and PowerPoint presentations for each chapter · Explosive and shock wave databases generated at the Los Alamos National Laboratory and the Russian Federal Nuclear Centers Charles Mader’s three-pronged approach – through text, computer programs, and animations – imparts a thorough understanding of new computational methods and experimental measuring techniques, while also providing the tools to put these methods to effective use.

Computer Simulation Of Shaped Charge Problems
Author: Wen Ho Lee
Publisher: World Scientific
ISBN: 9814478865
Category : Science
Languages : en
Pages : 396
Book Description
Devoted to the subject of shape charge design using numerical methods, this book offers the defense and commercial industries unique material not contained in any other single volume. The coverage of the Lagrangian and Eulerian methods as well as the equation of state provides first hand help to engineers working on shape charge problems.The book includes detailed descriptions of oil-well perforation not available from any other sources and, coupled with the material flow physics discussed in Chapters 2 and 3 and Appendix B, readers can design the fuel rod configurations for a nuclear reactor core. The equations of state and the constitutive models in Chapter 8 are among the best material models currently available.
