Pershing, David W. | Influence of fuel composition and flame temperature on the formation of thermal and fuel NOx in residual oil flames | A 900 kw model package boiler and a 20 kw laboratory tunnel furnace were used to study fuel and thermal NO, formation during heavy oil combustion. Package boiler results indicated that atomizer design, spray/ flow field interactions, and fuel composition were significant, dependent parameters. These... | Residual oil flames | 1979 |

Pershing, David W.; Slaughter, David Michael | Parameters influencing the evolution and oxidation of sulfur in suspension phase coal combustion | Stoker coal-fired boiler furnaces are significant in terms of coal consumption and environmental impact; however, they have received relatively little research attention. This paper describes the results of a two-year study on the formation of sulfur oxides in the suspension phase of a coal-fired s... | Stoker coal-fired furnaces | 1983 |

Sutherland, James Clayton; Kerstein, Alan R. | A unified approach to the various formulations of the one-dimensional-turbulence model | The One-Dimensional Turbulence (ODT) model has been successfully applied as a stand-alone model for predicting turbulence statistics in both nonreacting and reacting flows. There are several formulations of the model in the literature, and most of the variable-density formulations do not clearly dis... | | 2010 |

Eddings, Eric G.; Sarofim, Adel F. | Thermal behavior of a high-energy material immersed in a fire | One 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 |

Pershing, David W. | Control of NOx emissions | NITROGEN 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 combustion | 1980 |

Eddings, Eric G.; Sarofim, Adel F. | Modeling benzene and naphthalene formation in a premixed propylene flame | The 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 formation | 2005 |

Lighty, Joann; Sarofim, Adel F.; Eddings, Eric G. | Modeling the coagulation of charged particles | One 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; Modeling | 2004 |

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 furnace | Recent 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; Emissions | 1979 |

Whitty, Kevin J. | A system for measuring bubble voidage and frequency around tubes immersed in a fluidized bed of particles | Gas-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 |

Pershing, David W. | Influence of coal composition on the fate of volatile and char nitrogen during combustion | Fifty 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 emissions | 1982 |

Smith, Philip J. | Soot in combustion simulations | Soot 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 fires | 2005 |
