RISTraffic Performance Assessment Methodology of Degraded Roadway Links Following Hazards
Publisher: American Society of Civil Engineers
Abstract: Posthazard traffic networks are often disrupted, not only because of direct impacts on transportation infrastructure but also because of indirect impacts originating from the interdependent nature of infrastructure systems ...
Accessibility of Multimode Transport Facilities to Suburban Tourist Attractions: Analysis Based on Meso- or Microcommunity Scale in Beijing
Publisher: ASCE
Abstract: This paper aims to evaluate the accessibility of multimode transport facilities to suburban tourist attractions, under the background of detailed needs of tour transportation planning and urban development. Accessible, ...
A Novel Cooling Design and Improvement of a Radial-Inflow Turbine Rotor Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. With the continuous increase in turbine inlet temperature, traditional uncooled radial-inflow turbines are becoming inadequate for operation in higher-temperature environments. This study investigates both the ...
Effect of Three Dimensional Surface Topography on Gas Flow in Rough Micronozzles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The gas flow characteristics in rectangular cross section converging–diverging micronozzles incorporating the effect of threedimensional (3D) rough surface topography are investigated. The fractal geometry is utilized ...
Effects of Inhomogeneous Wind Fields on the Aerostatic Stability of a Long-Span Cable-Stayed Bridge Located in a Mountain-Gorge Terrain
Publisher: ASCE
Abstract: This study investigates the effects of inhomogeneous wind fields on the aerostatic stability of a long-span cable-stayed bridge, which straddles a typical mountain-gorge terrain. Inhomogeneous wind fields, with featured ...
Stress-Level Buffeting Analysis and Wind Turbulence Intensity Effects on Fatigue Damage of Long-Span Bridges
Publisher: ASCE
Abstract: Buffeting-induced vibration, which has a frequent occurrence and relatively large amplitude, may cause fatigue damage to the steel girder of long-span bridges. Buffeting is caused by random wind turbulence, and the turbulence ...
Exceedance Probability Assessment of Pedestrian Wind Environment Based on Multiscale Coupling Numerical Simulation
Publisher: ASCE
Abstract: This paper presents exceedance probability assessment, which is a statistical evaluation method for pedestrian wind environment based on numerical simulations with multiscale coupling techniques. The Meixi Lake community ...
Study on Mechanical Properties of Saline Soil and Evaluation of Influencing Factors
Publisher: ASCE
Abstract: In cold regions, the freeze–thaw (FT) cycle is a common natural physical process. It directly affects the stability of the project by changing the mechanical properties of the saline soil. Due to the presence of salt, the ...
An Aeroengine Internal Field Prediction Method Based on Principal Orthogonal Decomposition Dimensionality Reduction Integrated With Machine Learning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. To overcome the limitations of one-dimensional calculation and achieve rapid prediction of internal fields in aeroengines, this study adopts a method combining proper orthogonal decomposition and machine learning. ...
On a Curved Cavity Floor Design Based on Heat Transfer Coefficient Distribution for a Turbine Blade Squealer Tip
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The squealer tip has undergone extensive research and development in gas turbine blade applications. One of the persistent challenges is the high-temperature wear on the cavity floor, which has significant ...
