51 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
52 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
53 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
54 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
55 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
56 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
