This paper presents the hypergolic ignition test results of a potential environmentally friendly liquid propellant consisting of hydrogen peroxide oxidizer (with a concentration of 85%) and ethanolamine fuel for use in rocket engines. Open cup drop tests were conducted to study the effect of amount of metal salt catalyst in fuel and the initial temperatures of fuel and oxidizer on the ignition delay time. To test the hypergolic ignition of bipropellant formulation in a real rocket engine environment, a pressure-fed liquid propellant rocket engine (LPRE) was designed and developed. During the tests it was found that the amount of catalyst and the initial temperature of the fuel had a significant effect on the ignition delay of hypergolic bipropellant. However, the oxidizer temperature seemed to have almost no affect on the ignition delay. There was also significant difference between the ignition delay times from open cup tests and those from rocket engine static firings.

An investigation of two-phase slug flow in inclined pipelines Bağcı, Ali Suat (Informa UK Limited, 2004-06-01) Two-phase slug flow in inclined pipelines can cause significant practical operating problems. When slugs flow in an inclined pipeline that contains sections of different inclinations, they undergo a change of length and slug flow characteristics as the slug moves from section to section. In addition, slugs can be generated at low elbows, dissipate at top elbows and shrink or grow in length as they travel along the pipe. A mathematical model and a computer program were developed to simulate these phenomena. ...
A study on the effects of catalysts on pyrolysis and combustion characteristics of Turkish lignite in oxy-fuel conditions ABBASI-ATIBEH, Ehsan; Yozgatlıgil, Ahmet (Elsevier BV, 2014-01-01) The catalytic pyrolysis and combustion characteristics of low calorific value Turkish lignite in various ambient conditions were explored and the evolution of gases during pyrolysis tests was examined using a Thermogravimetric Analyzer coupled with a Fourier Transform Infrared spectrometer (TGA-FTIR). Potassium carbonate (K2CO3), calcium hydroxide (Ca(OH)(2)) and iron (III) oxide (Fe2O3) were employed as precursors of the catalysts and compared to the Raw-form (no catalyst added) to investigate the effects ...
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...
A study on the reactivity of various chars from Turkish fuels obtained at high heating rates Magalhaes, Duarte; Riaza, Juan; Kazanç Özerinç, Feyza (Elsevier BV, 2019-03-01) This work investigates the reactivity of chars produced from Turkish biomass and lignite fuels using a wire mesh reactor at high temperature and high heating rate. The fuels studied were olive residue, almond shell, and Soma lignite. Blends of Soma lignite-olive residue and Soma lignite-almond shell were prepared in proportions of 75:25 and 50:50 wt%, respectively. A wire mesh reactor is used for the pyrolysis of the samples in a controlled inert atmosphere at a uniform temperature of 1600 degrees C and at ...
PREDICTION OF BED MATERIAL ACTIVITY FROM CHANGES IN CARBON-DIOXIDE CONCENTRATION FOLLOWING COAL PARTICLE INJECTION IN THE FLUIDIZED-BED REACTOR VURAL, H (Elsevier BV, 1994-01-01) An electrically heated laboratory scale fluidized bed reactor was used for measurement of carbon dioxide concentrations from the devolatilization of bituminous coal under conditions pertinent to a large scale atmospheric pressure fluidized bed combustor (AFBC). Feeding a few particles into the bed, which contained 1 or 2 g of char, produced an increase in CO2 concentration. The quantity of CO2 released from the fluidized bed was found to be a function of fluidizing solid material, as well as the bed tempera...
