RISNumerical Investigation on the n-Heptane Spray Flame at Hydrous Ethanol Premixed Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In hydrous ethanol-diesel dual-fuel combustion modes, premixed hydrous ethanol would have an impact on the diesel combustion and soot production. In this work, based on computational fluid dynamics (CFD) model coupled with ...
Markov Nonlinear System Estimation for Engine Performance Tracking
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a joint state and parameter estimation method for aircraft engine performance degradation tracking. Contrast to previously reported techniques on state estimation that view parameters in the state ...
Energy Efficient Two Phase Microcooler Design for a Concentrated Photovoltaic Triple Junction Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The potential application of an R134acooled twophase microcooler for thermal management of a triple junction solar cell (CPV), under concentration of 2000 suns, is presented. An analytical model for the triplejunction solar ...
Two Phase Liquid Cooling for Thermal Management of IGBT Power Electronic Module
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent trends including rapid increases in the power ratings and continued miniaturization of semiconductor devices have pushed the heat dissipation of power electronics well beyond the range of conventional thermal ...
Prebending Coiled Tubing and Its Fatigue Life Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Coiled tubing is widely used in oil drilling and production operations. However, extreme high stress variation of coiled tubing during the processes of pulling out, rolling in the reel, and ...
Snap Transitions of Pressurized Graphene Blisters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blister tests are commonly used to determine the mechanical and interfacial properties of thin film materials with recent applications for graphene. This paper presents a numerical study on snap transitions of pressurized ...
The Mesoscale and Microscale Structure and Organization of Clouds and Precipitation in Midlatitude Cyclones. X: Wavelike Rainbands in an Occlusion
Publisher: American Meteorological Society
Abstract: The dynamical and microphysical structures of trains of wavelike rainbands in an occlusion are described. The rainbands were located in a region of potential instability behind the cold front aloft They were 3?5 km wide, ...
Global Synthesis for Face Milled Spiral Bevel Gears With Zero Transmission Errors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Local synthesis establishes a relationship between the relative motion and the local geometry properties of gear and pinion surfaces at one single (mean) point. Theoretically, local synthesis design of spiral bevel and ...
Unsteady Behaviors of Steam Flow in a Control Valve With T-Junction Discharge Under the Choked Condition: Detached Eddy Simulation and Proper Orthogonal Decomposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the practical space limitation, the control valve in industrial utilities is usually immediately followed by a short flow passage, which would introduce considerable complexity into highly unsteady flow behaviors, ...
Proper Orthogonal Decomposition and Extended- Proper Orthogonal Decomposition Analysis of Pressure Fluctuations and Vortex Structures Inside a Steam Turbine Control Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In steam turbine control valves, pressure fluctuations coupled with vortex structures in highly unsteady three-dimensional flows are essential contributors to the aerodynamic forces on the valve components, and are major ...
