RISSliding Wear of WC-Ni-Based Self-Lubricating Composites With the Addition of Fullerene-Like WS2 Nanoparticles Against WC-Ni Cermet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, WC-Ni-based composites with fullerene-like WS2 nanoparticles were fabricated by pulsed electric current sintering. High pressure could assist in low-temperature sintering of the composite. The sliding wear ...
Time Domain Approaches to the Stability Analysis of Flexible Dynamical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents two approaches to the stability analysis of flexible dynamical systems in the time domain. The first is based on the partial Floquet theory and proceeds in three steps. A preprocessing step evaluates ...
Research on Heat Transfer Model of Asphalt Pavements Subjected to Microwave Heating Recycling
Publisher: American Society of Civil Engineers
Abstract: In order to assess temperature field in microwave heating for recycling asphalt pavements, a 2D mathematic heat transfer model was developed based on Fourier heat transfer theory. The microwave internal heat-generation was ...

Tuning Elastic Waves in Soft Phononic Crystal Cylinders Via Large Deformation and Electromechanical Coupling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Soft electroactive materials can undergo large deformation subjected to either mechanical or electrical stimulus, and hence, they can be excellent candidates for designing extremely flexible and adaptive structures and ...
Tunable Two-Way Unidirectional Acoustic Diodes: Design and Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Predeformation simultaneously changes the effective material stiffness as well as the geometric configuration and therefore may be utilized to tune wave propagation in soft phononic crystals (PCs). Moreover, the band gaps ...
Tunable and Active Phononic Crystals and Metamaterials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far beyond those found in nature, through artificial design of the topology or ordered structure of unit cells. This emerging class of ...
Experimental Study on the Cavitation Characteristics of an Oil Jet Pump With Multiple Nozzles for the Lubrication System in a Steam Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cavitation characteristics of oil jet pumps with multiple nozzles were studied using high frequency response pressure transducers with Mobile DTE Light Oil in experiment, which has an environment the same as that in the ...
Simulation of an Industrial Tangentially Fired Boiler Firing Metallurgical Gases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In industrial environments, boiler units are widely used to supply heat and electrical power. At an integrated steel mill, industrial boilers combust a variable mixture of metallurgical gases combined with additional fuels ...
Numerical Model of Thermoelectric Topping Cycle of Coal Fired Power Plant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditional fossil fuel power generation process typically has low efficiency. Large amount of the energy loss in Rankine cycle steam turbines (ST) is due to the temperature difference between the combustion flame temperature ...
