This study has been conducted to evaluate the merits and limitations of a subsonic and a supersonic analysis method used frequently in Government and Industry for predicting aerodynamic characteristics. Specifically the Unified Subsonic-Supersonic Aerodynamic Computer Program (USSAERO) was evaluation at Mach 0.4 for the subsonic case. The Supersonic-Hypersonic Arbitrary Body Program (HABP) was evaluated for the supersonic case beginning at a low Mach number of 1.50 and systematically increasing to Mach 4.63. Model geometries have been restricted to simple axisymmetric ogive forebody cylindrical afterbody combinations to aid in the relative comparison of the method capabilities. For the supersonic comparisons a data base was selected that featured a wide variety of nose bluntness and fineness ratios to determine their impact on the analysis capabilities. Specific limitations of the methods are identified from comparisons with detailed bodyt pressure coefficient data.

This book provides a compact yet comprehensive overview of recent developments in collisional-radiative (CR) modeling of laboratory and astrophysical plasmas. It describes advances across the entire field, from basic considerations of model completeness to validation and verification of CR models to calculation of plasma kinetic characteristics and spectra in diverse plasmas. Various approaches to CR modeling are presented, together with numerous examples of applications. A number of important topics, such as atomic models for CR modeling, atomic data and its availability and quality, radiation transport, non-Maxwellian effects on plasma emission, ionization potential lowering, and verification and validation of CR models, are thoroughly addressed. Strong emphasis is placed on the most recent developments in the field, such as XFEL spectroscopy. Written by leading international research scientists from a number of key laboratories, the book offers a timely summary of the most recent progress in this area. It will be a useful and practical guide for students and experienced researchers working in plasma spectroscopy, spectra simulations, and related fields.
