Effects of Free-Stream Turbulence on the Instantaneous Heat Transfer in a Wall Jet Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This is a preliminary study in order to understand how free-stream turbulence increases heat transfer. Effects of free-stream turbulence on instantaneous heat transfer were investigated in a wall ...
A Guide to Uncertainty Analysis of Hot-Wire Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uncertainty analysis of hot-wire data in turbulent flows are made for time-averaging and real-time data reduction techniques. Equations of uncertainty are derived in general form for every step ...
A Model of the Enhancement of Combustion of Coal-Water Slurry Fuels Using High-Intensity Acoustic Fields
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Combustion of coal-water slurry fuels is simulated in the presence of high-intensity acoustic fields which increases heat and mass transfer from the droplets and particles, and thereby enhances ...
Prediction of Heat Transfer Characteristics for Discrete Hole Film Cooling for Turbine Blade Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A two-dimensional injection model is used with a two-dimensional low Reynolds number k-ε model boundary layer code. The three-dimensional effects of the discrete hole injection process are ...
Modeling Sulfur Dioxide Capture in a Pulverized Coal Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The formation and capture of sulfur dioxide in a pulverized coal combustor is investigated. A two-dimensional, steady, axisymmetric code, PCGC-2 (Pulverized Coal Gasification and Combustion—two ...
A Model of the Enhancement of Coal Combustion Using High-Intensity Acoustic Fields
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model for the enhancement of coal combustion in the presence of high-intensity acoustic fields has been developed. A high-intensity acoustic field induces an oscillating velocity over pulverized ...
Operating Experience With a Fluidized Bed Test Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents operating experience with a fluidized bed combustor burning various coals. The primary focus is on the effect of relevant coal properties on combustor performance. Tests were ...
Effect of an Acoustic Field on the Combustion of Coal Particles in a Flat Flame Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of an acoustic field on the enhancement of coal combustion are investigated. A flat flame burner using methane-air mixtures as the fuel is used for the experiments. Micronized coal ...
