Burning rate comparison of a mathematical model with experimental results for AP/HTPB/Iron oxide based composite propellants
Özcan, Serhat Cem.; Ulaş, Abdullah; Department of Mechanical Engineering (2019)
Ballistic properties play a crucial role for designing solid propellant rocket motors. Among those properties, burning rate is one of the most critical properties that must be known in order to predict the performance of the motor accurately. While various experimental methods such as Ballistic Evaluation Motor tests, strand burner experiments and full scale motor testing are used to obtain burning rate, these methods may lead to time and money consumption problems. In order to save time and reduce the cost...
Burning and sooting behavior of ethanol droplet combustion under microgravity conditions
Yozgatlıgil, Ahmet; CHOI, MUN YOUNG; KAZAKOV, ANDREI; DRYER, FREDERİCK L (2004-11-01)
In an effort to gain a better understanding of the burning and sooting behavior of ethanol, isolated droplet combustion experiments were performed in the 2.2-s drop tower at NASA Glenn Research Center. The measurement of the burning rate, soot standoff ratio, and soot volume fraction are described in which initial droplet diameter, oxygen concentration, and ambient pressure were varied. The experiments reveal that while ethanol droplets burn in 1-atm air without soot formation, luminous radiation from soot ...
Combustion Characteristics of Nanoaluminium-Based Composite Solid Propellants: An Overview
Jayaraman, Kandasamy; Sivakumar, Ponnurengam Malliappan; Zarrabi, Ali; Sivakumar, R.; Jeyakumar, S. (2021-05-01)
The nanosized powders have gained attention to produce materials exhibiting novel properties and for developing advanced technologies as well. Nanosized materials exhibit substantially favourable qualities such as improved catalytic activity, augmentation in reactivity, and reduction in melting temperature. Several researchers have pointed out the influence of ultrafine aluminium (similar to 100 nm) and nanoaluminium (<100 nm) on burning rates of the composite solid propellants comprising AP as the oxidizer...
Combustion characteristics and kinetic analysis of Turkish crude oils and their SARA fractions by DSC
Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2013-10-01)
In this study, two Turkish crude oils from southeastern part of Turkey and their saturate, aromatic, resin fractions were analyzed by differential scanning calorimetry (DSC). The experiments were performed at three different heating rates (5, 10, 15 A degrees C min(-1)) under air atmosphere. Two different reaction regions were observed from DSC curves due to the oxidative degradation of crude oil components. In the first reaction region, it was deduced that the free moisture, volatile hydrocarbons were evap...
Combustion behavior and kinetics of a Turkish lignite blended with biomass/magnesite dust
Yousefzad Farrokhi, Farshid; Kazanç Özerinç, Feyza; Department of Mechanical Engineering (2017)
This study investigated the effect of blending on the combustion behavior of Turkish lignite blended with biomass or magnesite dust using a thermogravimetric analyzer (TGA) under air atmosphere. The lignite used in this study is Tunçbilek lignite (TL), which is blended with the biomass types; olive residue (OR) and almond shell (AS), and the inorganic industrial waste, magnesite dust (MD). The blends are composed of various weight fractions of fuels, with a constant weight fraction of molasses (10 wt. %) as...
