User's Manual for the Flow-Field Diagnostics Code EMABIC (Emission/Absorption Inversion Codes)

Abstract

EMABIC is a system of computer codes designed for infrared radiation prediction and flow-field retrieval diagnostics of low-visibility propellant, tactical rocket motors plumes. Radiation prediction employs a coupled gas band model, single-scattering particle model. Retrieval is made for both gas and particle radial properties by iterative Abel inversion of transverse emission, transmittance, and laser scattering profiles obtained at two spectral positions where, respectively, both gas and particles radiate and absorb and where only particles radiate and absorb. EMABIC (Emission/Absorption Inversion Codes) consists of six main programs, 45 sub-programs, and three implied date transfer files. Brief descriptions of all of the codes are given, and detailed data preparation instructions for the six main programs are included. An example application to a minimum smoke propellant plume model containing H2O and Al2O3 as the gas and particle phases is made.
