TL;DR: In this paper, the authors investigated the modeling of counterflow diffusion flames in which the products of ammonium perchlorate (AP) combustion were counterflowed against an ethylene fuel stream and the two-dimensional problem can be reduced to a one-dimensional boundary value problem along stagnation point stream-line through the introduction of a similarity transformation.
Abstract: We investigated the modeling of counterflow diffusion flames in which the products of ammonium perchlorate (AP) combustion were counterflowed against an ethylene fuel stream The two-dimensional problem can be reduced to a one-dimensional boundary value problem along stagnation point stream-line through the introduction of a similarity transformation By utilizing recent developments in hydrocarbon, chlorine, NO x and AP kinetics, we formulated a detailed transport, finite-rate chemistry system for the temperature, velocity, and species mass fractions of the combined flame system A detailed soot model is included which can predict soot volume fractions as a function of the strain rate and the fuel mole fraction We compare the results of this model with a series of experimental measurements in which the temperature was measured with radiatin-corrected thermocouples and OH rotational population distribution: several important species were measured with planar laser-induced fluorescence, UV-visible absorption, and Raman spectroscopies: and the soot volume fraction was measured with laser-induced incandescence and visible absorption spectroscopy

TL;DR: In this article, a comparison of the properties of propellant containing solid and liquid ferrocene derivatives has been made with those containing Fe/sub 2/O/sub 3/ and n-butyl errocene, respectively.
Abstract: Some ferrocene derivatives like 2,4-dinitrophenylhydrazine derivative of acetyl ferrocene, 1-pyrrolidinylmethyl ferrocene, di-ter-butyl ferrocene and 1,3-diferrocenyl-l-butene (DFB) have been synthesised and characterised by infrared, nuclear magnetic resonance, ultraviolet, iron content, etc. To study the effect of their incorporation on performance, ammonium perchlorate/hydroxyl-terminated polybutadiene-based composite propellants containing these derivatives have been prepared and studied for burn rates, tensile strength and percentage elongation followed by their static test evaluation. A comparison of the properties of propellant containing solid and liquid ferrocene derivatives has been made with those containing Fe/sub 2/O/sub 3/ and n-butyl ferrocene, respectively. The data clearly indicates that these ferrocene derivatives are better than Fe/sub 2/O/sub 3/ and n-butyl errocene. Also, DFB is the best among these derivatives. Like composite propellants, DFB increases burn rate in fuel-rich propellants also.

TL;DR: In this paper, a series of ferrocene-based hyperbranched polyethers (HBPE-Fc) were synthesized by esterification of Ferrocenecarbonyl chloride and hyperbranched polyether, which exhibited good catalytic activity on the thermal decomposition of ammonium perchlorate (AP).
Abstract: A series of ferrocene-based hyperbranched polyethers (HBPE-Fc) with different ferrocene content were synthesized by esterification of ferrocenecarbonyl chloride and hyperbranched polyether (HBPE). 1H NMR and FT-IR were used to confirm the structure of HBPE and HBPE-Fc. GPC was used to calculate the molecular weights. The catalytic performance of the synthesized HBPE-Fc for thermal decomposition of ammonium perchlorate (AP) was investigated by TG and DTG techniques. The results showed that HBPE-Fc exhibited good catalytic activity on the thermal decomposition of AP. The influence factors on catalytic performances, such as substitution degree of ferrocene and mass ratio of AP/HBPE-Fc were discussed as well.
