An experimental study was conducted to evaluate the ignitibility of a family of potential gas-generator solid propellants under different CO(2) laser heat fluxes and chamber operating conditions. Six types of solid propellant were tested: one baseline and five variations. The ingredients of the baseline propellant were ammonium nitrate, guanidine nitrate, potassium nitrate, and polyvinyl alcohol. The other five propellant variations were obtained by adding different amounts of carbon black, ammonium perchlorate, RDX, and triamino guanidine nitrate to the baseline formulation. The propellants were tested in a high-pressure windowed strand burner, which was pressurized with either air or argon purge gases. Propellant ignition was accomplished by a 50-W CO(2) laser. The ignition delay times of the propellants were measured at pressures of 1 and 69 atm using high-speed video cameras. In this paper, the test results and comparison of the ignition and combustion characteristics of these propellants were presented.

Analytical investigation of wet combustion process for heavy oil recovery Bağcı, Ali Suat (Informa UK Limited, 2004-12-01) Analysis of combustion tube data produced from experiments performed under realistic reservoir conditions is currently the most valid method of investigating in-situ combustion process. In this study, the optimization of water-air ratio for B. Kozluca heavy crude oil, and the comparison of the performance of dry and wet forward combustion processes were studied. An analytical model was used to extend the laboratory results so that the oil production and steam zone volume can be estimated under field conditi...
Ballistic properties and burning behaviour of an ammonium perchlorate/guanidine nitrate/sodium nitrate airbag solid propellant Ulaş, Abdullah; Kuo, K. K. (Elsevier BV, 2006-10-01) An experimental investigation on the determination of ballistic properties and burning behavior of a composite solid propellant for airbag application was conducted. The experimental results were obtained using a high-pressure optical strand burner. Steady-state burning rates were determined for a pressure range of 20.8-41.5 MPa and initial propellant temperatures of -30 to +80 degrees C. For the pressure and temperature ranges tested, the temperature sensitivity was on the order of 1x10(-3) K-1. The pressu...
Thermal Analysis of Crude oil lignite mixtures by Differential Scanning Calorimetry Kök, Mustafa Verşan (Elsevier BV, 1994-04-01) Thermal characterization of lignite, crude oils and their 10 and 20% mixtures were investigated by differential scanning calorimetry (d.s.c.). The calorific value of the lignite increased in mixtures depending on the crude oil type. In pyrolysis runs, temperature ranges where distillation and visbreaking occur were identified for the crude oils studied. The effect of heating rate was also studied, and higher reaction temperatures and higher heat flow rates were observed at d.s.c. peak thermograms with incre...
DSC study on combustion and pyrolysis behaviors of Turkish crude oils Kök, Mustafa Verşan (Elsevier BV, 2013-12-01) This study focused on the investigation of non-isothermal thermal behavior and kinetics of Turkish crude oils under combustion and pyrolysis conditions using differential scanning calorimetry (DSC). On DSC combustion curves, two exothermic oxidation regions were detected known as low temperature (LTO) and high temperature oxidation (HTO). Again, two distinct reaction regions were revealed under pyrolysis conditions and DSC curves exhibited endothermic behavior for both the distillation and cracking regions....
NANOSTRUCTURE OF SOOT COLLECTED FROM ETHANOL DROPLET FLAMES IN MICROGRAVITY Park, Seul-Hyun; Choi, Mun Young; Yozgatlıgil, Ahmet (Informa UK Limited, 2009-01-01) The nanostructure of soot particles collected from spherically symmetric ethanol droplet flames were analyzed using a high resolution transmission electron microscopy (HRTEM). Nanostructure properties, including fringe length and curvature of carbon lamellae, were measured for soot particles collected in various inert environments. The sampling experiments were performed in the reduced gravity environments produced in the NASA 2.2 sec Droptower at the Glenn Research Center in Cleveland, Ohio. Microgravity d...
