Effects of OFA Ratio on Coal Combustion and NOx Generation of a 600-MW Downfired Boiler after Changing Air Distribution around Fuel-Rich Flow
Publisher: American Society of Civil Engineers
Abstract: Both experimentation and numerical simulations were conducted to study the effects of the overfire air (OFA) ratio on the coal combustion and NOx generation characteristics of a 600-MW downfired boiler after changing the ...
Transferability of Urban Arterial Safety Performance Functions between Shanghai and Guangzhou, China
Publisher: ASCE
Abstract: Safety performance functions (SPFs) are used in roadway infrastructure safety management for purposes such as crash contributing factor analysis and hazardous roadway section identification. However, due to the lack of ...
Weldability and Distortion of Mg AZ31-to-Galvanized Steel SPOT Plug Welding Joint by Cold Metal Transfer Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, cold metal transfer (CMT) plug welding of 1 mm thick Mg AZ31 to 1 mm thick hot-dipped galvanized mild steel (i.e., Q235) was studied. Welding tests were performed and the process variables optimized with Mg ...
Cold Metal Transfer Plug Welding of Aluminum AA6061-T6-to-Bare Mild Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It was known that it is challenging to join lapped aluminum and bare steel with cold metal transfer (CMT) process because of the formation of significant brittle intermetallics. In this study, another attempt was made to ...
Linking Emergence of the Central Pacific El Niño to the Atlantic Multidecadal Oscillation
Publisher: American Meteorological Society
Abstract: he ocean?atmosphere coupling in the northeastern subtropical Pacific is dominated by a Pacific meridional mode (PMM), which spans between the extratropical and tropical Pacific and plays an important role in connecting ...
Three-Dimensional Seepage Investigation of Riverside Tunnel Construction Considering Heterogeneous Permeability
Publisher: ASCE
Abstract: Seepage is a major concern during the construction of a riverside tunnel, because the seepage may cause both hydraulic and mechanical problems. At present, there are some well-accepted methods combining the hydraulic-mechanical ...
Model-Based Thermodynamic Analysis of a Hydrogen-Fired Gas Turbine With External Exhaust Gas Recirculation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Climate science shows that the limitation of global warming requires a rapid transition toward net-zero emissions of green house gases on a global scale. Expanding renewable power generation in a significant way is seen ...
Additive Manufacturing Processes for Infrastructure Construction: A Review
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) has had an enormous impact on the manufacturing sector. Its role has evolved from printing prototypes to manufacturing functional parts for a variety of applications in the automotive, aerospace, ...
Interannual Variability of Summer Tropical Cyclone Rainfall in the Western North Pacific Depicted by CFSR and Associated Large-Scale Processes and ISO Modulations
Publisher: American Meteorological Society
Abstract: AbstractThis study examines the interannual variability of summer tropical cyclone (TC) rainfall (TCR) in the western North Pacific (WNP) depicted by the Climate Forecast System Reanalysis (CFSR). This interannual variability ...
Infrared Drying Characteristics and Quality Variations of Lily Bulbs Under Blanching Pretreatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Infrared drying characteristics and quality variations (color change, hardness, contents of polyphenol and flavonoid) of lily bulbs under blanching pretreatment are investigated. Influences of parameters such as pretreatment ...
