RISTrailing Edge Perforation for Interaction Tonal Noise Reduction of a Contra-Rotating Fan
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study focuses on a passive noise abatement technique in a small contra-rotating fan, aiming at reducing the interaction noise between the two rotors through porous trailing edge (TE) treatment to the forward rotor. A ...
Passive Noise Reduction for a Contrarotating Fan
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There has been renewed interest in the contrarotating (CR) fan configuration in aviation and other applications where size and weight are important design factors. Contrarotation recovers swirl energy compared with the ...
Developing a Quality-Embedded EVM Tool to Facilitate the Iron Triangle in Architectural, Construction, and Engineering Practices
Publisher: American Society of Civil Engineers
Abstract: In modern architecture, engineering, and construction (AEC) practices, the Iron Triangle of schedule, cost, and quality remains the key measurement to gauge project success. Existing tools do not work well at monitoring ...
Evaluating the Combined Effects of Weather and Real-Time Traffic Conditions on Freeway Crash Risks
Publisher: American Meteorological Society
Abstract: AbstractThe study presented in this paper investigated the combined effects of environmental factors and real-time traffic conditions on freeway crash risks. Traffic and weather data were collected from a 35-km freeway ...
Design and Evaluation of Three-Phalange Underactuated Adaptive LSDH Finger
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of the terminal operation tool of the in-orbit service of the space station faces the difficult problem of complicated operation in a small space. Anthropomorphic hand tools operation has long been a controversial ...
A Modal Parameter Identification Method Based on Improved Covariance-Driven Stochastic Subspace Identification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the quantitative dynamic analysis of aero gas turbines, accurate modal parameters must be identified. However, the complicated structure of thin-walled casings may cause false mode identification and mode absences if ...
Spatial Temporal Stability of an Electrified Viscoelastic Liquid Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents theoretically the spatialtemporal instability behavior of an electrified viscoelastic liquid jet. Dimensionless parameters have been tested for their influence on the transition of absolute and convective ...
Instability of a Confined Viscoelastic Liquid Sheet in a Viscous Gas Medium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A linear analysis method was used to investigate the instability behavior of a viscoelastic liquid sheet moving through a viscous gas bounded by two horizontal parallel flat plates. The liquid sheet velocity profile was ...
Untitled
Publisher: American Society of Civil Engineers
Abstract: Failure to communicate effectively and poor project knowledge continue to plague the construction industry, particularly concerning delay management and cost control. This paper aims to empirically examine the influence ...
EnergyPlus Integration Into Cosimulation Environment to Improve Home Energy Saving Through Cyber-Physical Systems Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a co-simulation platform which combines a building simulation tool with a cyber-physical systems (CPS) approach. Residential buildings have a great potential of energy reduction by controlling home ...
