RISUse of a Bubble Tracking Method for Prediction of Downhole Natural Separation Efficiency
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For any pumping artificial lift system in the petroleum industry, the free gas significantly affects the performance of the pump and the system above the pump. A model, though not a complete ...
Nitrification/Denitrification in Intermittent Aeration Process for Swine Wastewater Treatment
Publisher: American Society of Civil Engineers
Abstract: A continuous-flow intermittent aeration (IA) process has been studied for nitrogen removal from anaerobically digested swine wastewater with high ammonium content. High nitrogen removal efficiency of average 91% total ...
Diagonal Cartesian Method for the Numerical Simulation of Flow and Suspended Sediment Transport over Complex Boundaries
Publisher: American Society of Civil Engineers
Abstract: There is increasing demand for simulation tools of flow and suspended sediment transport over complex boundaries in hydraulic engineering. The diagonal Cartesian method, which approximates complex boundaries using both ...
Future Changes and Controlling Factors of the Eight Regional Monsoons Projected by CMIP6 Models
Publisher: American Meteorological Society
Abstract: An accurate prediction of land monsoon precipitation (LMP) is critical for the sustainable future of the planet as it provides water resources for more than two-thirds of the global population. Here, we show that the ...
Residual Capacity of Axially Loaded Circular RC Columns after Lateral Low-Velocity Impact
Publisher: American Society of Civil Engineers
Abstract: RC bridge columns that are at risk for collision loading must be designed for lateral impact load. Because bridge columns must also support axial loads, evaluating the residual axial capacity and collapse risk of impact-damaged ...
Residual Capacity of Axially Loaded Circular RC Columns after Lateral Low-Velocity Impact
Publisher: American Society of Civil Engineers
Abstract: RC bridge columns that are at risk for collision loading must be designed for lateral impact load. Because bridge columns must also support axial loads, evaluating the residual axial capacity and collapse risk of impact-damaged ...
Fatigue Behavior of Integral Built-Up Box Y-Joints between Concrete-Filled Chords with Perfobond Ribs and Hollow Braces
Publisher: ASCE
Abstract: A novel integral built-up box Y-joint welded to rectangular hollow section braces and concrete-filled square hollow section chord stiffened by perfobond ribs was proposed and studied in fatigue. Eight specimens, including ...
Experimental Study of Impact Pressures on Deep Plunge Pool Floors Generated by Submerged Inclined Jets with Controlled Aeration
Publisher: ASCE
Abstract: Hydrodynamic pressures on a plunge pool floor due to submerged aerated jets are of interest in many engineering fields. For the present study, dynamic pressures on a deep plunge pool floor due to submerged inclined jets ...
Energy Efficient Metro Train Running Time Rescheduling Model for Fully Automatic Operation Lines
Publisher: ASCE
Abstract: Reducing energy consumption without degrading the normal operation of metro trains and service quality has received increasing attention. Besides, fully automatic operation (FAO), for which no drivers and crew attendants ...
Effects of Corrosion and Scouring on Barge Impact Fragility of Bridge Structures Considering Nonlinear Soil–Pile Interaction
Publisher: ASCE
Abstract: This paper investigates the effects of corrosion and scouring on the barge impact fragility of bridge structures. A typical four-span continuous reinforced concrete (RC) bridge is selected as the baseline structure, and a ...
