RISAnalysis of Heavily Loaded Tilted Pads Thrust Bearings With Large Dimensions Under TEHD Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Huge thrust bearings with centrally pivoted and tilted pads operating under heavy loads are analzyed using the (thermoelastohydrodynamic) TEHD-theory. The Reynolds equation, the energy equation of ...
Proton Exchange Membrane Fuel Cell Air Management in Automotive Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the state-of-the-art of air management in proton exchange membrane fuel cell (PEMFC), which is a challenge because commercial compressors and humidification systems are not ...
PEDOT:PSS/SWCNTs as a Transparent Electrode for Organic Photovoltaic Devices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We have fabricated a flexible organic solar cells, with an active layer of poly(3hexylthiophene) (P3HT) blended with Fullerene derivative [6,6]phenyl–C61–butyric acid methyl ester (PCBM) which was deposited by spin ...
2D Numerical Study on Tidal Circulation in Strait of Dover
Publisher: American Society of Civil Engineers
Abstract: A two-dimensional numerical study of the tidal circulation in the Strait of Dover is presented. In this study, a depth-averaged model, which employs a finite-difference, splitting technique was used. The present model was ...
Effect of the Back Surface Reflector and Passivated Rear Contacts With PERT Solar Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We use Silvaco software (atlas tcad) simulation to investigate the effect of dielectric layer deposed on rear surface of solar cells passivated emitter and rear totally diffused (PERT). For an improved performance for this ...
Independent Identification of Friction Characteristics for Parallel Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The compensation for friction or joint losses in robotic manipulators contributes to an important improvement of the control quality. Besides appropriate friction modeling, experimental identification ...
Thermohydrodynamic Analysis of Thrust-Bearing With Circular Pads Running on Bubbly Oil (BTHD-Theory)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper considers the steady-state bubble-thermohydrodynamic behavior of rigid circular pad thrust bearing and presents an iterative numerical scheme to solve the governing equations. The Reynolds ...
Thermohydrodynamic Performance of Thrust Bearings With Circular Tilted Pads Under the Presence of Air Gas Bubbles and Centrifugal Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the analysis of thrust bearings with tilted circular pads running under thermohydrodynamic conditions. During operation, a considerable quantity of air/gas bubbles is dispersed ...
Causal and Fault Trees Analysis of Proton Exchange Membrane Fuel Cell Degradation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a reliability approach to analyze the degradation of proton exchange membrane fuel cell. This approach is based on the dependability analysis tools such as the causal and fault trees to establish an ...
Measurements of Laminar Flame Speeds of Gas to Liquid Diesel Fuel Blends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work investigates the laminar flame speed, SN, of gastoliquid (GTL) fuel and its 50–50% by volume blends with conventional diesel, in a cylindrical bomb capable of measuring SN at different initial temperatures and ...
