RISHigh Rotation Number Effect on Heat Transfer in a Leading Edge Cooling Channel of Gas Turbine Blades With Three Channel Orientations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat transfer in a leading edge, triangularshaped cooling channel with three channel orientations under high rotation numbers is investigated in this study. Continuous ribs and Vshaped ribs (P/e = 9, e/Dh = 0.085), ...
Layout Optimization of Wave Energy Park Based on Multi-Objective Optimization Algorithm1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, both semi-analytical method and numerical simulation is applied to investigate the hydrodynamic behavior of large arrays of point-absorber wave energy converters (WECs). To analyze wave interactions among ...
Heat Transfer and Friction Measurement in Pin-Fin Arrays Under Mist Flow Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effects of air/water mist flow on endwall heat transfer in a square channel were experimentally investigated using infrared thermography. The purpose was to study the detailed heat transfer contour variation caused by the ...
Nonboiling Heat Transfer and Friction of Air/Water Mist Flow in a Square Duct With Orthogonal Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat transfer of air/water mist flow in a single-side heated vertical duct was experimentally investigated. The mist flow was produced by introducing fine dispersed water droplets into the air stream, and the water–air ...
Multigrain Smoothed Particle Hydrodynamics and Hertzian Contact Modeling of the Grinding Force in Atherectomy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigated the grinding force in rotational atherectomy, a clinical procedure that uses a high-speed grinding wheel to remove hardened, calcified plaque inside the human arteries. The grinding force, wheel ...

Experimental Study of Lubricant Distribution and Lubrication Enhancement Induced by Ball Bearing Cage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The bearing cage played a pivotal role in affecting the lubricant redistribution and lubrication states. In this study, a cage unit is incorporated into an optical ball-on-disc apparatus for the purpose of a quantitative ...
Effects of Leading Edge Shape on Effusion Film Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigated the effusion film cooling on a turbine leading edge model. The pressure-sensitive paint (PSP) technique was employed to analyze the film cooling effectiveness. Three different leading edge profiles ...
Analytical and Model Studies on Behavior of Rigid Polyurethane Composite Aggregate under Compression
Publisher: American Society of Civil Engineers
Abstract: To determine the mechanical behavior of rigid polyurethane composite aggregate (RPC) in compression, uniaxial compressive tests of RPC specimens, which were molded by reaction injection, were conducted under different ...
Experimental Investigation of Effusion Film Cooling on a Cylindrical Leading Edge Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effusion film cooling is effective for cooling high-temperature turbine blades because it requires less coolant and produces a more uniform temperature distribution than conventional film cooling. Effusion cooling for a ...
