Book Description
A structured package for radiation analysis, SPRADIAN, is developed and its application is presented. This study is primarily motivated by necessity of a quantitative analysis of severe radiative environment which the MESES-C capsule encounters during its reentry into the earth atmosphere. In comparison with other radiation programs, much attention is paid to extension of the temperature range up to 100,000 K, detailed treatment of UV and VUV radiation, and flexibility with applications. Incorporated into the programs are the bound-bound, bound-free, and free-free radiation from monatomic and diatomic species. The bound-bound radiation is calculated by the line-by-line method, while the others are computed using corresponding cross-sections which are evaluated by the quantum defect method. Two approximate models are introduced to integration of the radiative heat transfer equation over the shock layer in order to evaluate the radiative heat flux. Accuracy of the program is discussed, and the application to the MUSES-C radiation analysis is presented briefly.

Book Description
The high temperatures generated in gases by shock waves give rise to physical and chemical phenomena such as molecular vibrational excitation, dissociation, ionization, chemical reactions and inherently related radiation. In continuum regime, these processes start from the wave front, so that generally the gaseous media behind shock waves may be in a thermodynamic and chemical non-equilibrium state. This book presents the state of knowledge of these phenomena. Thus, the thermodynamic properties of high temperature gases, including the plasma state are described, as well as the kinetics of the various chemical phenomena cited above. Numerous results of measurement and computation of vibrational relaxation times, dissociation and reaction rate constants are given, and various ionization and radiative mechanisms and processes are presented. The coupling between these different phenomena is taken into account as well as their interaction with the flow-field. Particular points such as the case of rarefied flows and the inside of the shock wave itself are also examined. Examples of specific non-equilibrium flows are given, generally corresponding to those encountered during spatial missions or in shock tube experiments.

Book Description
These Proceedings contain the papers presented at the 4th International Symposium on Impact Engineering, held in Kumamoto, Japan, on 16-18 July 2001. The primary objective of the international series of Impact Engineering is to provide a forum for the presentation of recent progress in Impact Engineering and its related fields, both in terms of fundamental research and industrial application including automotive and aerospace engineering. This volume includes more than 150 papers presented at the Symposium which covers the latest updated research results in various series such as "testing methods and behavior of materials at high strain rates", "dynamic deformation and fracture under impact" and "explosion, shock wave and their applications" and others. This volume will serve as memoirs to these efforts for the scientists and engineers who are working in the field of mechanics and materials and others.
