A Dynamic System Model for Lubricated Sliding Wear and Running-In
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Running-in should be regarded as a self-adapting and convergent process of a dynamic system. The effect of surface roughness on dynamic behavior of a lubricated sliding wear system has been ...
Combustion Technology for Low-Emissions Gas-Turbines:Selected Phenomena Beyond NOx
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since recent reviews cover the issues in NOx formation under gas-turbine canditions, and since regulations essentially dictate use of the premixed mode of combustion for minimum NOx , this ...
Combustion Technology for Low-Emissions Gas-Turbines: Some Recent Modeling Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computer modeling of low-emissions gas-turbine combustors requires inclusion of finite-rate chemistry and its intractions with turbulence. The purpose of this review is to outline some recent ...
In Situ X-Ray Computed Tomography Experiment on Mesodamage Evolution of Subgrade Bimsoil during Cycle Loading
Publisher: American Society of Civil Engineers
Abstract: This work revealed the mesodamage evolution in blocks-in-matrix soils (bimsoils) under triaixal cyclic loading. Although the macroscopic cyclic stress-strain responses of bimsoil have been well investigated, the mesoscopic ...
Numerical Wave Tanks Based on Finite Element and Boundary Element Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work forms part of an investigation into the nonlinear interaction between steep (but not overturning) transient waves and flared structures, using a coupled finite element and boundary ...
Detecting and Predicting Early Faults of Complex Rotating Machinery Based on Cyclostationary Time Series Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vibration signals of complex rotating machinery are often cyclostationary, so in this paper one novel method is proposed to detect and predict early faults based on the linear (almost) periodically ...
Coupled Lagrangian Monte Carlo PDF–CFD Computation of Gas Turbine Combustor Flowfields With Finite-Rate Chemistry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A coupled Lagrangian Monte Carlo Probability Density Function (PDF)-Eulerian Computational Fluid Dynamics (CFD) technique is presented for calculating steady three-dimensional turbulent reacting flow ...
Characterizing Economic Disruption with the Global Economic Disruption Index
Publisher: American Society of Civil Engineers
Abstract: Impacts of disasters are seen through the lens of death, dollars, and downtime, but downtime eludes quantification. This paper presents (1) the Global Economic Disruption Index (GEDI) as a method of describing the ...
