Measurement of Coherent Thermal Emission Due to Magnetic Polaritons in Subwavelength Microstructures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spectral and directional control of thermal emission is critically important for applications such as space cooling and energy harvesting. The effect of magnetic polaritons (MPs) on spectral modulation has been analyzed ...
The Analysis of Constrained Impulsive Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impulsive problems for mechanical systems subject to kinematic constraints are discussed in this paper. In addition to the applied impulses, there may exist suddenly changed constraints, or termed impulsive constraints. ...
Centrifuge Modeling of a Constructed Reservoir Embankment: Antiliquefaction Performance Improvement Using Nanoparticles
Publisher: American Society of Civil Engineers
Abstract: Antiliquefaction performance improvement for developed sites beneath existing structures has drawn increasing public attention to meet stricter requirements of seismic protection. Liquefaction mitigation using nanoparticles ...
Performance of Near Field Thermophotovoltaic Cells Enhanced With a Backside Reflector
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermophotovoltaic (TPV) systems are very promising for waste heat recovery. This work analyzes the performance of a nearfield TPV device with a gold reflecting layer on the backside of the cell. The radiative transfer ...
Creep Life Prediction for Aero Gas Turbine Hot Section Component Using Artificial Neural Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate and reliable component life prediction is crucial to ensure safety and economics of gas turbine operations. In pursuit of such improved accuracy and reliability, modelbased creep life prediction methods have become ...
Cooling Injection Effect on a Transonic Squealer Tip—Part II: Analysis of Aerothermal Interaction Physics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A basic attribute for turbine blade film cooling is that coolant injected should be largely passively convected by the local base flow. However, the effective working of the conventional wisdom may be compromised when the ...
Cooling Injection Effect on a Transonic Squealer Tip—Part I: Experimental Heat Transfer Results and CFD Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies have demonstrated that the aerothermal characteristics of turbine rotor blade tip under a transonic condition are qualitatively different from those under a low-speed subsonic condition. The cooling injection ...
Wideband Tunable Omnidirectional Infrared Absorbers Based on Doped Silicon Nanowire Arrays
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study considers the directional and spectral radiative properties of vertically aligned, heavily doped silicon nanowires for applications as broadband infrared diffuse absorbers. The nanowire array is modeled ...
Experimental Study on a Medium Consistency Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental testing rig is built to study the performance of a centrifugal pump used in medium consistency technology (MC technology). Pump performances are tested in different pulp concentration, degas pressure ...
Evaluation of CLASS 2.7 and 3.5 Simulations of Snow Properties from the Canadian Regional Climate Model (CRCM4) over Québec, Canada
Publisher: American Meteorological Society
Abstract: now cover simulations from versions 2.7 and 3.5 of the Canadian Land Surface Scheme (CLASS) coupled to the Canadian Regional Climate Model, version 4 (CRCM4), are evaluated over northern Québec and the larger Québec domain ...
