ABSTRACT
This part introduction presents an overview of the key concepts discussed in the subsequent chapters of the third part of the book. The part of the book discusses the basic radiation properties necessary for calculating radiative fluxes in gases with inclusion of molecular-band and atomic(ionic)-line absorption mechanisms. It reviews the methods currently available to calculate both radiative fluxes and their divergence for various gas systems with real emission and absorption spectra. The part presents major radiative heat transfer results obtained for both ablating and nonablating bodies in hypersonic flows of inviscid and viscous fluid. It is concerned with a relatively new, but important subject of probe shape optimization with respect to radiative fluxes. The part surveys hyperbolic entry studies for giant planets, in which ablation effects are large enough to influence the aerodynamics and thereby the trajectory of the entry body.
