2 Experimental and modeling study of particulate formation in high-pressure diesel-like conditions2000particulate formation; high-pressure diesel-like conditions; diesel combustion process; tailpipe particulate emissionsThe diesel combustion process has been characterized by combined measurements of flame intensity and extinction in the UV-visible range in an optically accessible divided-chamber diesel engine at different air/fuel ratios and constant engine speed, using n-heptane and commercial diesel oil as fuels....
3 Fine particle emissions from residual fuel oil combustion: Characterization and mechanisms of formation2000fine particle emissions; residual fuel oil combustion; airborne fine particulate matter (PM); particulate characteristics of PMThe characteristics of particulate matter (PM) emitted from residual fuel oil combustion in two types of combustion equipment were compared. A small commercial 732 kW rated fire-tube boiler yielded a weakly bimodal particulate size distribution (PSD) with over 99% of the mass contained in a broad co...
4 Formation pathways of ethynyl-substituted and cyclopenta-fused polycyclic aromatic hydrocarbons2000formation pathways of aromatic hydrocarbons; aromatic hydrocarbons; ethynyl-substituted aromatic hydrocarbons; cyclopenta-fused polycyclic aromatic hydrocarbons; PAH; ethynyl-PAHTwo novel classes of polycyclic aromatic hydrocarbons (PAH), those with ethynyl substituents (ethynyl- PAH) and those with externally fused five-membered rings (cyclopenta-fused PAH or CP-PAH), have recently been identified in the products of a variety of fuels and combustion/pyrolysis environments....
5 Mechanism and kinetics of lead capture by kaolinite in a downflow combustor2000mechanism and kinetics; lead capture; kaolinite; downflow combustor; postflame reaction; lead vaporAn 18 kW, 6 m long, gas-fired downflow combustor was used to examine the postflame reaction between lead vapor and kaolinite. Since the focus of this work was to evaluate the reaction with lead vapor, samples were extracted at a temperature above the metal dew point. The sample was rapidly diluted w...
6 Modeling the rich combustion of aliphatic hydrocarbons2000rich combustion; aliphatic hydrocarbons; kinetic mechanism; benzene formation; high-molecular-mass aromatic compoundsA new kinetic mechanism has been developed for the formation of benzene and high-molecular-mass aromatic compounds in rich flames of aliphatic hydrocarbons. The kinetic scheme emphasizes both the role of resonantly stabilized radicals in the growth of aromatics and the standard acetylene addition me...
7 Modeling the vaporization of ash constituents in a coal-fired boiler2000vaporization of ash constituents; coal-fired boiler; minimizing harmful emissions; vaporizationEmissions of fine particulate and trace toxic metals are being subjected to increasing regulation. This paper addresses how the emission of these compounds can be influenced by changes in combustion conditions, particularly those selected to minimize NOx emissions. The vaporization and condensation ...
8 On the relevance of surface growth in soot formation in premixed flames2000surface growth; soot formation; premixed flames; surface growth mechanisims; particle mass accumulationThe role of surface growth mechanisms in particle mass accumulation was investigated in rich, premixed, ethylene/air flames from non-sooting to moderately sooting conditions using in situ optical diagnostics and predictions from a detailed chemical kinetic model. Particles formed just after the flam...
9 The partitioning of arsenic during pulverized coal combustion2000arsenic partitioning; arsenic; pulverized coal combustion; coal-fired electric utility; coal; arsenic volatilization; volatilized arsenic.An important issue facing the coal-fired electric utility industry is the environmental impact resulting from the release of arsenic contained in the coal. Depending on the forms of occurrence in the coal and transformation mechanism involved, arsenic-containing compounds may exit the furnace in the...
10 State space sensitivity to a prescribed probability density function shape in coal combustion system: Joint B-PDF versus clipped Gaussian PDF2000space sensitivity; coal combustion; b-PDF mixing model; three coal-off gas; pulverized-coal research furnaceThe turbulent transport of three coal off-gas mixture fractions is coupled to a prescribed joint b-probability- density-function (b-PDF) mixing model. This physical transport and subgrid joint b-PDF mixing model is used to explore the incorporation of coal off-gas compositional disparities between t...
11 Urban planning tools for quality growth2000Formed in January of 1997, Envision Utah is a public/private community partnership dedicated to studying the effects of long-term growth in the Greater Wasatch Area of northern Utah. Sponsored by the Coalition for Utah's Future, Envision Utah and its partners - with extensive input from the public -...
12 Demographic trends affecting public education in Utah2000-11Beginning in 2004 and continuing for at least a decade, the school age population (5 to 18 year olds) in Utah will increase significantly. Throughout the 1990s, the school age population in Utah grew more slowly than did the population in general so that its share in the total population declined. T...
13 Petroleum technology advances through applied research by independent oil producers2000-01petroleum technology; independant oil producers; National Oil Research Program"Petroleum Technology Advances Through Applied Research by Independent Oil Producers" is a program of the National Oil Research Program, U.S. Department of Energy. Between 1995 and 1998, the program competitively selected and costs shared twenty-two projects with small producers. The purpose was to ...
14 Population projections for Utah's cities & unincorporated Areas 2000-20302000-06Utah's seven associations of government1 have produced these city and unincorporated area population projections for each year from 2000 through 2005 and for the years 2010, 2020, and 2030. These are consistent with the county population projections produced by the Governor's Office of Planning and ...

16 University of Utah Professors Emeriti Club: A brief history, 1965-19992000-06University of Utah, alumni; University of Utah, societies, etc.; Universities and colleges, alumni and alumnaeCompiled history of the Professors Emeriti Club at the University of Utah from 1965-1999
17 Method of reducing moisture and solid content of bitumen extracted from tar sand minerals2000-02-01Tar sand; Alkoxyalkylphenol alkoxylate surfactant; Recoverable hydrocarbon; Anionic and cationic flocculant; Bitumen; Moisture reductionTar sand is upgraded to produce a hydrocarbon having a low concentration of water and solids by contacting a bitumen/diluent mix with an alkoxyalkylphenol alkoxylate surfactant prior to separation of a recoverable hydrocarbon phase. The separation of the bitumen/diluent mix into a recoverable hydroc...
