51 Eddings, Eric G.; Sarofim, Adel F.; Pugmire, Ronald J.Selection of surrogates for jet fuelsAbstract: A. detailed characterisation of JP fuels is provided based on literature data for the average of 55 worldwide and 4 US Jet-A fuels. These are complemented by NMR analysis of a JP-8 that provides the fractions of the carbon in the fuel that are present as protonated, bridgehead, and non-sub...Jet propulsion fuel; Surrogates; Simulations2008
52 Sarofim, Adel F.Simulation of soot formation using particle dynamics with one dimensional nucleation modeTwo soot formation models using particle dynamics with one-dimensional nucleation mode directly coupled with gas phase chemistry are tested on three ethylene and three methane laminar premixed flames. These models demonstrate strength in the prediction of concentration profiles of major combustion p...Soot formation models; Particle dynamics; One dimensional nucleation mode; Combustion chemistry2004
53 Smith, Philip J.Soot in combustion simulationsSoot is the dominant source of radiative heat transfer from most practical flames. A review is presented of historical, empirical modelling approaches for estimating heat flux from fires and flames. These historical methods have drawn on empiricism to address the role of soot while seeking methods f...Large eddy simulation; LES; Combustion simulation; Radiative heat transfer; Pool fires2005
54 Eddings, Eric G.; Spinti, Jennifer C.; Smith, Philip J.Soot volume fraction from extinction in JP-8 and heptane pool firesTotal extinction measurements from a multiple beam experiment using a 10mW laser diode are presented and compared to calculate soot volume fraction in heavily sooting pool fires from a 150 mm diameter pan of Jet Propulsion fuel 8 (JP-8) and heptane. Trends in attenuation are critiqued for the t...Pool fires; Jet propulsion fuel2005
55 Eddings, Eric G.; Smith, Philip J.Soot volume fraction from extinction in JP-8 and heptane pool firesTotal extinction measurements from a multiple beam experiment using a 10mW laser diode are presented and compared to calculate soot volume fraction in heavily sooting pool fires from a 150 mm diameter pan of Jet Propulsion fuel 8 (JP-8) and heptane.

56 Veranth, John M.; Pershing, David W.; Sarofim, Adel F.Sources of unburned carbon in the fly ash produced from low-NOx pulverized coal combustionThe unburned carbon in the fly ash produced from low-NOx pulverized coal combustion is shown to consist of a mixture of soot and coal char. The soot was identified by the presence of chains or aggregates of 10-50-nm-diameter primary particles in electron microscope images of both laboratory sample...Unburned carbon; Char1998
57 Smith, Philip J.State space sensitivity to a prescribed probability density function shape in coal combustion systems: joint β-PDF versus clipped Gaussian PDFThe turbulent transport of three coal off-gas mixture fractions is coupled to a prescribed joint //-probability- density-function (//-PDF) mixing model. This physical transport and subgrid joint //-PDF mixing model is used to explore the incorporation of coal off-gas compositional disparities betwe...Off-gas stream; β-PDF; Char oxidation2000
58 Eddings, Eric G.The potential of on-line optical flow measurement in the control and monitoring of pilot-scale oxy-coal flamesDigital image processing techniques oer a wide array of tools capable of extracting apparent displacement or velocity information from sequences of images of moving objects. Optical flow algorithms have been widely used in areas such as traffic monitoring and surveillance. The knowledge of instantan...2014-01-01
59 Lighty, JoannThe role of open innovation in development of futuristic technologies for carbon capture in coal-fired power plants: an academic perspectiveCoal is an important fossil fuel resource for electricity generation which also contributes to significant CO2 emissions. The process of capturing carbon dioxide for utilization and sequestration is an important area of research in this domain. Academia-industry collaborations are playing a signific...2012-01-01
60 Eddings, Eric G.; Sarofim, Adel F.Thermal behavior of a high-energy material immersed in a fireOne of the uncertainties in the calculations of time-to-explosion for containers of high-energy materials immersed in fires is that of the thermal boundary at the container-explosive interface. Understanding this interface is critical in evaluating risks, safety issues and prevention mechanisms. In ...2004
61 Ring, Terry ArthurValidation of energy moments from the one-dimensional energy dependent neutron diffusion equation, MCNP5 and Attila-7.1.0 with the GODIVA experimentNormalized neutron energy moments (moments) from the one-dimensional energy dependent neutron diffusion equation (EDNDE), Monte Carlo N Particle 5 version 1.40 (MCNP5) and Attila-7.1.0-beta version (Attila) are validated with the GODIVA experiment (GODIVA). Energy moments 0-5 for all three methods a...2012-01-01
62 Ring, Terry ArthurVerification of analytic energy moments for the one-dimensional energy dependent neutron diffusion equation with MCNP5 and Attila-7.1.0The energy dependent neutron diffusion equation (EDNDE) is converted into a moment equation which is solved analytically for the 1-D problem of a bare sphere of pure 235U. The normalized moments 0-5 generated analytically are compared to normalized energy moments, from Monte Carlo N Particle 5 versi...2012-01-01
