RISAnalysis of Combined Backward-Forward Extrusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The upper bound approach is used to analyze combined backward-forward extrusion. The deformation region is divided into five zones separated by planer and cylindrical surfaces of velocity ...
Tip Clearance and Tip Vortex Cavitation in an Axial Flow Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A combined study of tip clearance and tip vortex cavitations in a pump-type rotating machine is presented. Cavitation patterns are observed and cavitation inception is determined for various gap ...
Development of a Dry Ultra-Low NOx Double Swirler Staged Gas Turbine Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the development of an ultra-low NOx gas turbine combustor for cogeneration systems. The combustor, called a double swirler staged combustor, utilizes three-staged premixed ...
Fractographic Study of Fatigue Crack Propagation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fractographic studies were carried out on fatigue fracture of aluminum alloys and carbon steels. Special attention was given to the correlation between striation spacing and macroscopic crack ...
The Drag and Added-Mass Coefficients of Various Buffers Vibrating Axially in Water
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to analyze the longitudinal vibration of a pipe-string for mining mineral resources at deep-sea bottoms, the fluid forces acting on the buffer and pump-module attached to the pipe-string ...
Fluid-Soil-Structure Interaction in Liquefaction around a Cyclically Moving Cylinder
Publisher: American Society of Civil Engineers
Abstract: Coastal or offshore structures such as pipelines installed on the seabed are submitted to cyclic horizontal loads either by the direct hydrodynamic action of waves or through the cyclic movement of risers or flow lines ...
Development of Evaluation Technologies for Microtubular SOFCs Under Pressurized Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We developed evaluation technologies for microtubular solid oxide fuel cells under pressurized conditions. The pressurized cell evaluation system for the single cell was produced. The chamber ...
La0.6Sr0.4Co0.2Fe0.8O3–Ag Composite Cathode for Intermediate-Temperature Solid Oxide Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The composite electrode of La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) and Ag was examined as an air electrode for intermediate-temperature solid oxide fuel cells. Two types of LSCF/Ag composite electrodes were ...
Power Generation Properties of Microtubular Solid Oxide Fuel Cell Bundle Under Pressurized Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A microtubular solid oxide fuel cell (SOFC) bundle was developed based on a new design. Anode-supported microtubular SOFCs with the cell configuration, La0.6Sr0.4Co0.2Fe0.8O3 (LSCF)-Ce0.9Gd0.1O1.95 ...
Development of Air-Cooled Ceramic Nozzles for a Power-Generating Gas Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of air-cooled ceramic nozzle vanes for a power-generating gas turbine has been reported. To make up the limited temperature resistance of present ceramic materials, the utilization ...
