RISAn Improved Design of Gravity Compensators Based on the Inverted Slider-Crank Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The static balancing of mechanical systems is an important issue because it allows one to significantly decrease the size of actuators for equivalent displacements of the end effector. Indeed, the actuators do not have to ...

An Eddy-Viscosity Model Sensitized to Curvature and Wall-Roughness Effects for Reynolds-Averaged Closure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new extension of the realizable K−ε model that accounts for streamline curvature, system rotation, and surface roughness. The model is a type of realizable K−ε model, but the transport equations and ...
Numerical Study of Bifurcation Structures in Reflected Shock-Wave/Laminar-Boundary-Layer Interaction Within an End-Wall Tube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The primary aim of this study is to analyze the unsteady characteristics of the interaction between a reflected shock wave and a laminar boundary layer in an end-wall shock tube. Our direct numerical simulations at shock ...
The Role of Mineral Aerosol in Tropospheric Chemistry in East Asia—A Model Study
Publisher: American Meteorological Society
Abstract: A detailed gas-phase chemistry mechanism is combined with dust surface uptake processes to explore possible impacts of mineral dust on tropospheric chemistry. The formations of sulfate and nitrate on dust are studied along ...
Baroclinic Adjustment in an Atmosphere–Ocean Thermally Coupled Model: The Role of the Boundary Layer Processes
Publisher: American Meteorological Society
Abstract: aroclinic eddy equilibration and the roles of different boundary layer processes in limiting the baroclinic adjustment are studied using an atmosphere?ocean thermally coupled model. Boundary layer processes not only affect ...
Baroclinic Eddy Equilibration under Specified Seasonal Forcing
Publisher: American Meteorological Society
Abstract: Baroclinic eddy equilibration under a Northern Hemisphere?like seasonal forcing is studied using a modified multilayer quasigeostrophic channel model to investigate the widely used ?quick baroclinic eddy equilibration? ...
A Scale Adaptive Turbulence Model Based on the k Equation and Recalibrated Reynolds Stress Constitutive Relation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An algebraic relationship between turbulent dissipation rate and von Karman length are used to dismiss the transport equation of turbulent dissipation rate in standard k−خµ (SKE) turbulence model. Meanwhile, a recalibrated ...
The Role of Boundary Layer Processes in Limiting PV Homogenization
Publisher: American Meteorological Society
Abstract: A ?-plane multilevel quasigeostrophic channel model with interactive static stability and a simplified parameterization of atmospheric boundary layer physics is used to study the role of different boundary layer processes ...
A Simple Palladium Hydride Embedded Atom Method Potential for Hydrogen Energy Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When hydrogen is produced from a biomass or coal gasifier, it is necessary to purify it from syngas streams containing components such as CO, CO2, N2, CH4, and other products. Therefore, a challenge related to hydrogen ...
