RISNonequilibrium Thermal Fluctuations of Flow in Thermal Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fouling is detrimental to the heat transfer performance of concentrated solar power plant components where heat exchange takes place with the cooling tower water. Wave elements cause an expression of deep insight of the ...
A Novel Three-Loop Parallel Robot With Full Mobility: Kinematics, Singularity, Workspace, and Dexterity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel parallel robot, dubbed the SDelta, is the subject of this paper. SDelta is a simpler alternative to both the well-known Stewart–Gough platform (SGP) and current three-limb, full-mobility parallel robots, as it ...
Full-Mobility Three-CCC Parallel-Kinematics Machines: Kinematics and Isotropic Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The subject of this paper is twofold: the kinematics and the isotropic design of six degrees-of-freedom (DOF), three-CCC parallel-kinematics machines (PKMs). Upon proper embodiment and dimensioning, the PKMs discussed here, ...
Thermal and Flow Characteristics of Water–Nitrogen Taylor Flow Inside Vertical Circular Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat transfer and flow characteristics of Taylor flows in vertical capillaries with tube diameters ranging from 0.5 mm to 2 mm were studied numerically with the volume of fluid (VOF) method. Streamlines, bubble shapes, ...
Fabrication of Foamed Polyethersulfone–Zeolite Mixed Matrix Membranes for Polymer Electrolyte Membrane Fuel Cell Humidification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polymer electrolyte membrane (PEM) fuel cell efficiency must be improved in order to become cost competitive with fossil fuel-based technologies. Approaches to increasing cost efficiency include raising fuel cell operating ...
Thick Anvils as Viewed by the TRMM Precipitation Radar
