51 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
52 Pershing, David W.Control of NOx emissionsNITROGEN OXIDES (NOX) are produced in combustion from molecular nitrogen (thermal NOx) or from oxidation of nitrogen contained in the fuel (fuel NOx). Production of NOx in a turbulent diffusion flame is largely dependent upon fuel composition and fuel/air contacting, which for liquid fuels is determ...Staged heat release; Tunnel furnace; Boiler simulator; Staged combustion1980
53 Eddings, Eric G.; Sarofim, Adel F.Modeling benzene and naphthalene formation in a premixed propylene flameThe Utah Surrogate Mechanism was used to model a fuel-rich, non-sooting premixed laminar flame of propylene at 5000 Pa with an equivalence ratio of 2.32. The simulation results were found to be satisfactory in comparison with the experimental data. For example, the measured concentration profiles of...Utah Surrogate Mechanism; Propylene; Combustion modeling; Benzene formation; Naphthalene formation2005
54 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
55 Ring, Terry ArthurRoom temperature co-precipitation synthesis of magnetite nanoparticles in a large pH window with different basesMagnetite nanoparticles (Fe3O4) represent the most promising materials in medical applications. To favor high-drug or enzyme loading on the nanoparticles, they are incorporated into mesoporous materials to form a hybrid support with the consequent reduction of magnetization saturation. The direct sy...2013-01-01
56 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
57 Smith, Philip J.Reduced-order PCA models for chemical reacting flowsOne of the most challenging aspects of turbulent combustion research is the development of reduced-order combustion models which can accurately reproduce the physics of the real system. The identification and utilization of the low dimensional manifolds in these system is paramount to understand and...2014-01-01
58 Lighty, Joann; Sarofim, Adel F.; Eddings, Eric G.Modeling the coagulation of charged particlesOne important mechanism in the growth of soot particles is to understand the role of particle charge in the coagulation of the particles. A previously developed model has been extended to include the coagulation of charged particles. The model includes neutral particles and charged particles (up to ...Charged particles; Flame ionization; Modeling2004
59 Pershing, David W.; Wendt, Jost O. L.Investigation of first- and second-stage variables on control of NOx emissions using staged combustion in a pulverized coal wall-fired furnaceRecent tests on an EPA 1- to 1.5 x 106 Btu/hr pilot-scale pulverized coal furnace show that N0X emissions of 100 ppm to 150 ppm (zero percent 02) are achievable with the use of two-stage combustion. Comparable N0X emission levels were obtained with three different coal types fired in either the sing...NOx; Carbon monoxide; Emissions1979
60 Whitty, Kevin J.A system for measuring bubble voidage and frequency around tubes immersed in a fluidized bed of particlesGas-solid fluidized beds are common in chemical processing and energy production industries. These types of reactors frequently have banks of tubes immersed within the bed to provide heating or cooling, and it is important that the fluid dynamics within these bundles is efficient and uniform. This p...2010
61 Pershing, David W.Influence of coal composition on the fate of volatile and char nitrogen during combustionFifty coals from North America, Europe, Asia, South Africa and Australia were burned in a 21 kW, refractory-lined tunnel furnace to determine the influence of coal properties on the fate of volatile and char nitrogen. Excess air fuel NO emissions (as determined by combustion in Ar/02/C02) ranged fro...Coal composition; Char nitrogen; Volatile nitrogen; NO emissions1982
62 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
