RISResearch on Deflagration Hazard and Its Influencing Factors on Urban Gas Pipeline
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the hazard criteria for thermal radiation and shock wave overpressure applicable to the deflagration of urban gas pipelines have been proposed. The phast software is used to analyze the hazard intensity and ...
Study on the Burst Pressure and Failure Mechanism of Pipelines with a Kinked Dent–Corrosion Defect Based on Element Birth and Death Technique
Publisher: American Society of Civil Engineers
Abstract: AbstractExisting studies on dent-corrosion defect suffer from two main limitations. First,
the simulation approach of imposing a dent onto a precorroded pipe fails to replicate
the actual sequence of defect formation. ...
Wave Propagation Through a Micropolar Slab Sandwiched by Two Elastic Half Spaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of wave propagation through a micropolar elastic slab sandwiched by two classical elastic halfspaces is studied in this paper. Different from the classical elastic solids, the particle in micropolar solids can ...
Weak El Niño and Winter Climate in the Mid- to High Latitudes of Eurasia
Publisher: American Meteorological Society
Abstract: According to the sea surface temperature anomaly (SSTA) intensity in the Niño-3.4 region and the east?west gradient across the Pacific, three types of El Niño are identified in this work. An event with larger than average ...
Effect of Matrix Alloying on Braking Performance of Copper-Based Brake Pad Under Continuous Emergency Braking
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The continuous emergency braking performance of copper-based brake pads alloyed with different Ni contents were tested. The results showed that the copper-based brake pad with high Ni content exhibits improved stability ...
Experimental Study of Turbulent Flow and Heat Transfer Behaviors Over a Micro-Rib-Dimple-Structured Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was conducted to characterize the evolution of turbulent boundary layer flow over a micro-rib-dimple-structured surface. In addition to measuring the surface pressure distribution and detailed flow ...
Experimental and Numerical Study of the Turbulent Flow and Heat Transfer in a Wedge-Shaped Channel With Guiding Pin Fin Arrays Under Rotating Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments and numerical simulations under stationary and rotating conditions have been conducted to investigate turbulent flow and heat transfer characteristics of innovative guiding pin fin arrays in a wedge-shaped ...
Risk Analysis of Gas Pipeline in Karst Area Based on Multilevel Hierarchical Structure Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a risk analysis method of gas pipeline in karst area based on the integrated model of the decision-making trial and evaluation laboratory–interpretive structural model (DEMATEL– ISM) method and the cross-impact ...
Experimental and Numerical Simulation Studies on Water and Salt Migration in Loess-Like Sulfate Saline Soils under Evaporation Conditions
Publisher: American Society of Civil Engineers
Abstract: AbstractLoess-like sulfate saline soils are prevalent in the arid and semiarid regions of
northwest China. Their engineering properties are highly unstable due to the dynamic
interactions among water, heat, salt, and energy, ...
Optimization Model for Arterial Signal Coordination Considering Platoon Dispersion Suppression
Publisher: American Society of Civil Engineers
Abstract: AbstractPlatoon dispersion is a major challenge for arterial coordination control. In practice,
extending main road green time is often used to accommodate dispersion; however, this
approach lowers green time utilization ...
