“…The evaluation uses the BAM (Band modeling)-code (21,22) of ICT to model bands of reaction products. The code calculates NIR/IR-spectra (1±10 mm) of inhomogeneous gas mixtures of H 2 O (with bands around 1.3, 1.8, 2.7 and 6.2 mm), CO 2 (with bands near 2.7 and 4.3 mm), CO, NO and HCl considering also emission of soot particles.…”

“…Analysis of the spectral characteristics of flame radiation is important in many applications such as propellant, incineration, etc. [3][4][5]. In particular, for the propellants such as plume or pyrotechnic mixture such as countermeasure flare, spectroscopic investigation will be an efficient method to evaluate their performances.…”

Measurement of the radiative characteristics of a flame is important in the field of combustion diagnostics to better understand combustion processes, fuel performance, and combustion engine efficiency. Flame emissivity is one of the most important parameters for investigating such characteristics. This paper proposes a method to directly measure the effective spectral emissivity of a hot burnt gas in flame. We calibrate the radiometric measurement of a mid-infrared (IR) emission spectrometer using a directly heated graphite blackbody in a national standards laboratory, and determine the flame temperature by fitting the spectrum detected with the emission spectrometer to the color ratio calculated with HITEMP using the species concentrations predicted by ICT thermodynamic calculation. For proof of concept, we determine the spectral effective emissivity of the flame of an IR countermeasure flare in the spectral range of 2-5 mm. We estimate the uncertainty in the measurement to be 11.48 %.

“…Harwell [2] used the infrared radiation detector to test the radiation intensity of the monitor in the plume field. Deimling [3] used the spectrometer to test the infrared radiation spectral characteristics from 1.2 micro to 14 micron of 3 different types of solid propellants Devir [4] used the FTIR and FLIR to test the infrared radiation intensity from 1.5 micron to 5.5 micron and the infrared radiation images for a small solid rocket motor.…”

The infrared radiation signature of the plume from the solid propellants of different energy characteristics is not the same. Three kinds of double-base propellants of different energy characteristics were chosen to test the infrared spectral radiance from 1000 cm -1 to 4500 cm -1 of their plume. The radiative spectrum was obtained in the tests. The experimental results indicate that the infrared radiation of the plume is basically determined by the energy characteristic of the propellant. The radiative transfer calculation models for the exhaust plume from the solid propellants were established By inducing the chemistry reaction source term and the radiation source term into the energy equation, the plume field and the radiative transfer were solved in a coupling way. The calculated results were consistent with the experimental data, so the reliability of the calculation models was conformed. The temperature distribution and the extent of the afterburning of the plume are distinct for the propellants of different energy characteristics, therefore the radiation of the plume varied with the propellants. The temperature of the fluid cell in the plume will increase or decrease to some extent by the influence of the radiation source term. NomenclatureI λ = spectral radiance I = radiation intensity E = radiative illumination/energy of the fluid θ = zenith angle φ = azimuth angle ρ = density of the fluid T = temperature of the fluid v = velocity of the fluid p = pressure of the fluid 1 Ph.
