ULTRA-DILUTE COMBUSTION OF PRIMARY REFERENCE FUELS

Combustion Science and Technology, 2007
Abstract Using n-heptane and iso-octane as gasoline surrogate fuels, the laminar flame speeds, flame thicknesses, reaction zone thicknesses, and flammability limits of fuel/air/residual gas mixtures are computationally studied over ranges of pressures, temperatures, and dilution levels representative of unthrottled HCCI operation.

Biodiesel and Fuel Dilution of Engine Oil

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">In this work fuel dilution of engine oil, and the impact of biodiesel fuel on dilution, were examined. New emissions requirements have driven the adoption of a range of aftertreatment systems for diesel engines.

Dilute Ethanol Fueled SOFCs: A Symbiotic Solution Strategy

ASME 2009 7th International Conference on Fuel Cell Science, Engineering and Technology, 2009
Biofuels have been broached as being more commercially viable under the biorefinery concept wherein multiple product streams enhance overall economics. An example of this concept is presented in which solid oxide fuel cells (SOFCs) and bioethanol are explored in light of the symbiotic pairing of these two promising alternative energy thrusts.

Fuel Dilution and Liquid Fuel Operational Effects on Ultra-High Thermal Intensity Distributed Combustor

50th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2012
Abstract Ultra-high thermal intensity colorless distributed combustion has been examined for methane and methane diluted with air, nitrogen or carbon dioxide gas and liquid fuel (ethanol) burning in air at a fixed thermal load. Fuel was diluted with inert gases and air to simulate the combustion of low heating value fuels with special focus on the ...

MILD combustion in diffusion-controlled regimes of Hot Diluted Fuel

Combustion and Flame, 2012
Reactive structures have been characterized in a steady laminar, unidimensional mixing layer on a dense grid of parameters in moderate or intense low-oxygen dilution (MILD) combustion conditions with hot and diluted fuel. The structures have been studied in terms of temperature and heat release profiles in a mixture fraction space for various ranges of

The robotized chemical treatment of diluted spent fuel samples prior to isotope dilution analysis

Journal of Radioanalytical and Nuclear Chemistry Articles, 1996
A system made up by a Zymark robot and a separation automate preteats spent fuel samples and monitors a tri-n-octylphosphine oxide column extraction chromatographic procedure in order to isolate and purify uranium and plutonium present in the samples, prior to the spectrometric measurements.

DILUTION OF ENGINE LUBRICANTS BY FUEL

SAE Technical Paper Series, 1920
<div class="htmlview paragraph">Engine lubrication troubles resulting from the dilution of the lubricating oil in engine crankcases appear with increasing frequency, particularly where economy demands the use of cheap grades of fuel. Unless a lubricant not miscible with present engine fuels can be produced, lubricants will steadily decrease in ...

Homogeneous-Dilution Model of Partially-Fueled Pulse Detonation Engines

42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004
A model requiring no empirical parameter for estimating the propulsive performances of a partially-fueled (P-F) pulse detonation engine (PDE) was proposed. The model was developed based on a hypothesis that every performance parameters obtained by integrating phenomena in one cycle are predominantly determined by energetics only.

Modeling of a dilute vaporizing multicomponent fuel spray

International Journal of Heat and Mass Transfer, 1987
Abstract A simplified spray environment is used to represent the multicomponent nature of liquid fuels and to examine the sensitivity of their vaporization behavior to the various liquid- and gas-phase models. Liquid-phase models are the diffusion limit, the infinite diffusion, and the vortex.

Investigation of fuel dilution in ethanol spray MILD combustion

Applied Thermal Engineering, 2019
Abstract MILD combustion is a promising technique for low heating value fuels. In this paper, spray MILD combustion of diluted liquid fuel is numerically studied. The modelling framework is based on the RANS approach, the EDC combustion model with a skeletal chemical mechanism, and the Lagrangian tracking of droplets. The validated numerical model is
