Numerical Modeling of Space Plasma Flows, ASTRONUM-2009
"This Volume contains the proceedings of ASTRONUM-2009 -- the fourth in a series of international conferences now organized by the Center for Space Plasma and Aeronomic Research at the University of Alabama in Huntsville and the Laboratory for Research into the Fundamental Laws of the Universe at the French Commissariat of Atomic Energy. The subjects of the conference included such topics as turbulence and cosmic ray transport, astrophysical flows, space plasma flows, kinetic and hybrid simulations, numerical methods, algorithms, and frameworks, and data handling and visualization. All of these topics are of great importance for scientists investigating solar structure, the heliosphere, the Sun-Earth connection, and various astrophysical phenomena. The problems discussed at the conference are characterized by different time and space scales, regions, or particle populations, for which different sets of defning equations or concepts are necessary to understand the physical system in its entirety. This book will be of interest to specialists in applied mathematics, astrophysics, space physics, and computer science working on the application of novel numerical algorithms to contemporary problems arising in these fields. It can also be used by graduate students to get acquainted with the fundamental approaches to solving the fluid dynamic and kinetic equations governing space plasma flows."--Publisher's website.
Magnetohydrodynamic Modeling of the Solar Corona and Heliosphere
The book covers intimately all the topics necessary for the development of a robust magnetohydrodynamic (MHD) code within the framework of the cell-centered finite volume method (FVM) and its applications in space weather study. First, it presents a brief review of existing MHD models in studying solar corona and the heliosphere. Then it introduces the cell-centered FVM in three-dimensional computational domain. Finally, the book presents some applications of FVM to the MHD codes on spherical coordinates in various research fields of space weather, focusing on the development of the 3D Solar-InterPlanetary space-time Conservation Element and Solution Element (SIP-CESE) MHD model and its applications to space weather studies in various aspects. The book is written for senior undergraduates, graduate students, lecturers, engineers and researchers in solar-terrestrial physics, space weather theory, modeling, and prediction, computational fluid dynamics, and MHD simulations. It helps readers to fully understand and implement a robust and versatile MHD code based on the cell-centered FVM.
Numerical Modelling of Astrophysical Turbulence
Author: Wolfram Schmidt
language: en
Publisher: Springer Science & Business Media
Release Date: 2013-09-20
In this "SpringerBrief" the author considers the underlying problems and questions that are common to numerical models of turbulence in different astrophysical systems. Turbulence has emerged as an important research topic in several areas of astrophysics. Understanding and modeling turbulence is particularly important for the dynamics of the interstellar medium, but also for the intergalactic medium, as well as in stars. The advancement of methods for numerical simulations of astrophysical turbulence, however, is still challenging because of gravity, strong compressibility, magnetic fields, and other effects. The book begins with a review of general aspects of numerical simulations of turbulence. In the main part the author presents findings from his numerical studies on astrophysical turbulence and discusses the astrophysical implications. He also explains in detail the numerical schemes utilized. Readers will find that this book offers a compact yet comprehensive introduction.
