RISRestrained Torsion of Thin-Walled Beams
Publisher: American Society of Civil Engineers
Abstract: A first-order torsion formulation for closed thin-walled (CTW) beam subjected to restrained torsion is developed to consider the warping deformation and restrained shear stresses on cross section and their effect on the ...
A Density Functional Theory Study on the Diffusion of Fission Gas Atoms in Uranium Dioxide
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uranium dioxide (UO2) is the typical fuel that is used in the current nuclear power plant; fission gas atoms are produced during and after the nuclear reactor operation; the fission gas atoms have a significant effect on ...
Investigation and Application of Bio-Inspired Microscale Structures to Turbine Endwall for Enhancing Film Cooling Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, inspired by micro-scale surface structure patterns of birds’ flight feather, a novel thermal-protection enhancement technique is proposed for a turbine endwall with cavity air leaked from an upstream realistic ...
Film Cooling on Turbine Vane Endwalls With Different Inlet Cooling Configurations: Experimental and Computational Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comparative study of turbine endwall film cooling resulting from three different cooling configurations in front of the passage inlet was conducted. The three inlet cooling configurations considered in this study were a ...
An Active Phantom Cooling Concept for Turbine Endwall Cooling From Pressure-Surface Film Coolant Injection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cooling of the endwall of a nozzle guide vane should receive special attention due to its uniqueness of near-wall complex secondary flows and concomitant challenge of offering film-coverage for cooling the endwall pressure-side ...
Assessment of Aerosol Modes Used in the MODIS Ocean Aerosol Retrieval
Publisher: American Meteorological Society
Abstract: oastal and island Aerosol Robotic Network (AERONET) sites are used to determine characteristic aerosol modes over marine environments. They are compared with the assumed modes used in the operational Moderate Resolution ...
Sputtering of Graphite by Hydrogen Isotopes in the Fusion Environment: A Molecular Dynamics Simulation Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sputtering of graphite due to the bombardment of hydrogen isotopes is crucial to successfully using graphite in the fusion environment. In this work, we use molecular dynamics to simulate the sputtering using the ...
Can Eddy Fluxes Serve as a Catalyst for Hurricane and Typhoon Formation?
Publisher: American Meteorological Society
Abstract: Numerical simulations and diagnostics are performed for Typhoon Tip and Tropical Storm Faye, both of which occurred during 1979, the year of the First Global GARP (Global Atmosphere Research Program) Experiment (FGGE). The ...
Comparisons of Endwall Overall Effectiveness From Two Film Hole Distribution Patterns at Low and High Exit Mach Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, detailed overall cooling effectiveness and associated flow patterns are presented for two distinct film hole distribution patterns over a turbine endwall: an axial-row pattern and an iso-Mach number line row ...
