METHODS OF ADAPTIVE MESHES IN GAS DYNAMIC PROBLEMS

Moscow, Nauka, Publishing Company Fizmatlit, 2000, 247pp.

ISBN 5-9221-0060-2

Readership: Scientists, engineers, graduate and postgraduate students dealing with computational simulation. Summary: An application of adaptive meshes to gas dynamic problems is considered. The aeroelasticity problems with relative large displacement of interacting medium (the geometrically adaptive meshes), and the gas dynamic problems with multy-scale flow structure (dynamically adaptive mashes) are considered, where the methods of adaptive meshes are especially effective. The scheme of Arbitrary Lagrangian Eulerian (ALE) method and high accuracy TVD scheme are used. Multiple in one- and two-dimensional (flat, axially-symmetric) problems are solved using geometrically and dynamically adaptive meshes. Contents: Foreword. General statements about adaptive meshes. Introduction. Adaptive meshes. Geometrically adaptive meshes. Essentials of the numerical method for solving problems of interaction of a gas with deformable bodies.
