Abstract

A computational model is developed for the regression rate of flare surface area to compute the IR intensity versus burn time for various configurations of flare pellets. 10 g of MTV composition filled in the diameter (Dia) 20 mm tube was fired to obtain Linear Burn Rate (LBR) and IR intensity in 1.8–2.6 µm and 3–5 µm waveband using Dual band radiometer. The calorific value in the Oxygen (O₂) atmosphere was measured for the composition using the bomb calorimeter. Model I predicts the average emissivity of two different LBR pyrotechnic MTV compositions in two wavebands. Using computed data, Model II calculates the IR intensity versus burn time in each waveband for configurations of flare pellets of circular (Dia 26 and Dia 36 mm), square(1″×1″×8″) and rectangular (2″×”1″×8″) using shrinking core model coupled with IR intensity equations. Radiometric data were generated for the two compositions. The calculated data were found to be in close agreement with that of the radiometric data for peak IR intensity and burn time for various flare configurations. Radiometric studies along with computational prediction for modified MTV composition have been carried out for various configurations. The predicted data from the computational model has been supported with the prediction of the species chemical composition at equilibrium using the REAL Thermochemical code.

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
