Evolution of temperature of a droplet of liquid composite fuel interacting with heated airflow
Thermophysics and Aeromechanics, 2016The macroscopic patterns of a temperature change at the center of a droplet of three-component (coal, water, petroleum) composite liquid fuel (CLF) were studied using a low-inertia thermoelectric converter and system of high-speed (up to 105 frames per second) video recording during the induction period at different heating intensity by the air flow ...

Effect of Gas Diffusion Layer Composition on the Performance of Liquid Direct Methanol Fuel Cells
ECS Transactions, 2009The effect of gas diffusion layer compositions on the performance of liquid feed direct methanol fuel cell has been investigated. Cathode diffusion layers consisting of carbon paper with different microporous layer compositions have been fabricated. Specifically, we have modified the carbon material used in microporous layers.

In this study, the response of a liquid-fueled resonant pulse combustor to changes in liquid fuel composition was investigated. Experiments were performed with gasoline- ethanol, gasoline-diesel, and gasoline-heptane mixtures selected to produce meaningful variations in the ignition delay time. A review of ignition quality tester (IQT) data provided an

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]).

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 ...

Abstract A sheet moulding compound (SMC) of fibre-glass and ortho-phthalic polyester has been pyrolysed in a laboratory installation at 300, 400, 500, 600 and 700°C for 30 min. Solid residues of 72–82 wt%, gas yields of 6–12 wt% and liquid yields of 9–13 wt% were obtained.

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 ...

Puffing/micro-explosion of two-liquid droplets: Effect of fuel shell composition
Physics of FluidsTheoretical research into the heat and mass transfer, hydrodynamic and physicochemical processes in combustion chambers of gas turbine engines usually implies that multi-component jet fuels are modeled using single-component liquids (saturated or cyclic hydrocarbons) and their substitutes.

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.
