RISHydrodynamic Fluid Pressure in Grinding Zone During Grinding With Metal-Bonded Diamond Wheels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental and theoretical studies on hydrodynamic fluid pressure were conducted for the cases of plane grinding with nonporous metal bonded diamond wheels of SD140 and SD4000. Hydrodynamic ...
Transitional Strategy for Annular Lift Fan Aircraft to Lower the Momentum Drag and Pitching Moment
Publisher: ASCE
Abstract: The annular lift fan aircraft is a new conceptual vertical takeoff and landing (VTOL) vehicle for which the tremendous momentum drag and pitching moment in transition is a big problem to overcome. In this study, different ...
Liquefaction of Unsaturated Sands
Publisher: American Society of Civil Engineers
Abstract: Recent laboratory tests and field observations have revealed that unsaturated sands are susceptible to liquefaction. Systematic investigation of liquefaction potential of unsaturated sands is, however, lacking. In this ...
Numerical Research of Thermo–Hydro–Mechanical Response and Heat Transfer in a Multiwell EGS with Rough-Walled Fractures after Shear Deformation
Publisher: ASCE
Abstract: Natural fractures may not be developed in hot dry rock reservoirs, and tectonism or fracturing can induce the shear deformation of fractures and result in large-scale rough-walled fractures. Previous studies usually ignore ...
Shallow Turbulent Flow Simulation Using Two-Length-Scale Model
Publisher: American Society of Civil Engineers
Abstract: Numerical simulations of the planar starting jets were conducted using a two-length-scale turbulence model and a hydraulic code to study the effect of friction on 2D turbulence in shallow open-channel flow. The simulation ...
Incorporating Woodwork Fabrication into the Integrated Teaching and Learning of Civil Engineering Students
Publisher: American Society of Civil Engineers
Abstract: As an alternative to the traditional structural analysis adopting computer-aided modeling and evaluation, this pedagogical research provides an integrated teaching and learning approach by mapping cognitive domains in a ...
A Microencapsulated PhaseChange Material SuspensionBased Integrated Thermal Management System for Extended Range Electric Vehicle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to improve the temperature maintenance capacity for the battery of the extendedrange electric vehicle (EREV) in a lowtemperature environment, a microencapsulated phasechange material suspension (MPCMS)based ...
Modeling and Cycle Parameter Matching of a High-Speed Variable Cycle Turbofan-Ramjet Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variable cycle turbofan-ramjet (VCTR) engine is a promising propulsion system candidate for future Mach 4+ vehicles. Compared with conventional turbine engines, the VCTR engine has a higher thrust-to-weight ratio, a smaller ...
A Hybrid Algorithm Based on GRNN and Grasshopper Optimization Algorithm for Welding Nugget Diameter Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Resistance spot welding (RSW) is applied extensively by automotive manufacturers for assembling the structural and body components of vehicles. The current method of welding quality inspection is off-line inspection after ...
Safety-Risk Transmission Assessment Based on a Factor–Event Network for Metro Construction Projects
Publisher: ASCE
Abstract: Metro construction projects are accompanied by numerous unpredictable risk factors and risk events. Traditional safety risk analysis of metro construction projects focuses on risk factors of a particular risk event, such ...
