Blowout Sensitivities in a Liquid Fueled Combustor: Fuel Composition and Preheat Temperature Effects
Volume 4A: Combustion, Fuels and Emissions, 2017The objective of this paper is to identify the influence of fuel composition on blowoff limits in a liquid fueled combustor. In premixed, gaseous systems, blowoff is a kinetically limited phenomenon, possibly with additional heat loss effects. In liquid fueled systems, the situation is far more complex, as a variety of processes can influence blowoff ...

Fuel composition stabilization in a subcritical liquid-salt transplutonium burner reactor
Atomic Energy, 2012Possible replenishment schemes ensuring the attainment and maintenance of an equilibrium fuel composition are studied for a subcritical liquid-salt transplutonium burner reactor now under development. The computational model describes fuel burnup in a two-component approximation singling out the transplutonium actinides and the remaining actinide ...

Solid State Ionics, 2021
Abstract Elevating the operating temperature of polymer electrolyte fuel cells (PEFCs) can facilitate the reaction kinetics and improve the CO tolerance of catalysts, and simplify the complex water-heat management system of fuel cells. In this study, we fabricated the ionic liquid-based polymer electrolyte that can operate up to 250 °C without ...

Polyimide/ionic liquid composite membranes for fuel cells operating at high temperatures
Electrochimica Acta, 2014Abstract Supported ionic liquid membranes (SILMs) were prepared by impregnating a porous Matrimid ® membrane with protic room-temperature ionic liquids (RTILs): 1-n-methylimidazolium dibutylphosphate ([C 1 im][DBP]), 1-n-butylimidazolium dibutylphosphate ([C 4 im][DBP]) and 1-n-butylimidazolium bis(2-ethylhexyl)phosphate ([C 4 im][BEHP]).

Analytical Chemistry, 1983
The use of a NMR spectrometer as a continuous flow liquid chromatographic detector (LC//sup 1/H NMR) generates a proton spectrum of each hydrocarbon class present in the sample. A detailed set of equations is presented which permits LC//sup 1/H NMR integration data from petroleum fuels to be interpreted as an average composition for each ...

Carbonate-tin composite liquid anode for solid oxide direct carbon fuel cell
International Journal of Hydrogen Energy, 2017Abstract The SnO2 blocking film deposited on the anode-electrolyte interface during operation degrades the performance of a liquid tin (Sn) anode direct carbon fuel cell (DCFC). In the present study, Li–K carbonate is introduced to solve the SnO2 problem. A composite anode composed of molten carbonate and Sn was fabricated.

Novel Composite Membranes Based on Polyaniline/Ionic Liquids for PEM Fuel Cells Applications
Key Engineering Materials, 2020The modern development of (PEMFCs) is still faced by several obstacles such as membrane cost and performance. Perfluorosulfonic acid membranes (e.g. Nafion of DuPont) are currently the most successful in PEMFCs. PEMFCs usually operate at temperatures around 80°C and at atmospheric pressure.

Ceramic Matrix Composite Applications in Advanced Liquid Fuel Rocket Engine Turbomachinery
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education, 1992Hot gas path components of current generation, liquid fuel rocket engine turbopumps (T/P) are exposed to severe thermal shock, extremely high heat fluxes, corrosive atmospheres and erosive flows. These conditions, combined with high operating stresses, are severely degradative to conventional materials.

Differences in the ignition characteristics of coal–water slurries and composite liquid fuel
Solid Fuel Chemistry, 2016The processes of the inert heating, ignition, and combustion of the drops of typical coal–water slurries and promising composite liquid fuel were experimentally studied with the use of high-speed (to 105 frame/s) video recording facilities. The particles of brown and black coals with of sizes 80–100 μm were used as the basic components of the coal ...

Determination of liquid and solid phase composition in partially frozen middle distillate fuels
Fuel, 1987Abstract A liquid-solid separator apparatus was constructed and a method developed for the separation and characterization (g.c.-m.s.) of the crystals and liquid from partially frozen middle distillate fuels. The filtrate data were straightforward, but the precipitate presented problems in interpretation since the waxy crystals entrapped significant ...
