The hydrodynamic and radiation processes accompanying explosions of chemical explosives and fuel-air mixtures have been considered.
Computer modeling of the radiation from a fire ball of explosion and a flame of diffusion combustion of a hydrocarbon fuel
has been performed. The dependences of the heat flux density from the region occupied by explosion and combustion products
on its temperature and geometric characteristics have been determined. Thermal load distributions on targets of different
orientations in the vicinity of the energy release zone have been obtained. A comparison of the thermal parameters on radiation
detectors with the criteria of thermal affection of people and ignition of combustible materials has been made.

[Show abstract][Hide abstract] ABSTRACT: This paper describes the status of the 2008 edition of the HITRAN molecular spectroscopic database. The new edition is the first official public release since the 2004 edition, although a number of crucial updates had been made available online since 2004. The HITRAN compilation consists of several components that serve as input for radiative-transfer calculation codes: individual line parameters for the microwave through visible spectra of molecules in the gas phase; absorption cross-sections for molecules having dense spectral features, i.e. spectra in which the individual lines are not resolved; individual line parameters and absorption cross-sections for bands in the ultraviolet; refractive indices of aerosols, tables and files of general properties associated with the database; and database management software. The line-by-line portion of the database contains spectroscopic parameters for 42 molecules including many of their isotopologues. (c) 2009 Elsevier Ltd. All rights reserved.

[Show abstract][Hide abstract] ABSTRACT: A new molecular spectroscopic database for high-temperature modeling of the spectra of molecules in the gas phase is described. This database, called HITEMP, is analogous to the HITRAN database but encompasses many more bands and transitions than HITRAN for the absorbers H2O, CO2, CO, NO, and OH. HITEMP provides users with a powerful tool for a great many applications: astrophysics, planetary and stellar atmospheres, industrial processes, surveillance, non-local thermodynamic equilibrium problems, and investigating molecular interactions, to name a few. The sources and implementation of the spectroscopic parameters incorporated into HITEMP are discussed.
