RISInvestigations of 3D Turbulent Flow Inside and Around a Water-Jet Intake Duct Under Different Operating Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper the flow field in the intake duct of a model water-jet unit is studied by using a commercial 3D CFD code. In order to model the intake duct/hull interaction, the computational ...
Snow and Ice Melting Performance Evaluation and Economic–Environmental Assessment of a Novel Steel Slag–Based Composite Phase Change Aggregate Asphalt Pavement
Publisher: ASCE
Abstract: The traditional mechanical equipment/chemical salt approach for pavement snow/ice removal is costly and may cause serious environmental pollution problems. To facilitate the pavement snow/ice melting in a more economical ...
Differential Settlement and Induced Structural Damage in a Cut-and-Cover Subway Tunnel in a Soft Deposit
Publisher: American Society of Civil Engineers
Abstract: This study investigated the differential settlement and induced structural damage in the west extension of Nanjing Metro Line 1. The minimum and maximum cumulative settlements measured over the course of four years of ...
Experimental and Analytical Study of Jacking Load during Microtunneling Gongbei Tunnel Pipe Roof
Publisher: American Society of Civil Engineers
Abstract: This paper presents a case study on the jacking load during the installation of Gongbei tunnel pipe roof using microtunneling. The pipe roof, consisting of 36 pieces of 1,620-mm-diameter steel pipes along a curved alignment, ...
Wetting Behavior and Failure Mechanism of Asphalt–Aggregate Interface Based on Molecular Dynamics Simulations
Publisher: American Society of Civil Engineers
Abstract: AbstractEnvironmental factors, such as aging and water, can lead to the failure and damage
of the asphalt–aggregate interface, accelerating the occurrence of asphalt pavement
diseases. This study investigates the wetting ...
Synthesis and Characterization of a High-Performance Asphalt Modified with Lignin–Waste Cooking Oil Composite
Publisher: American Society of Civil Engineers
Abstract: As one of the most important aromatic renewable natural resources, lignin has the potential to improve the high-temperature rheological properties and antiaging properties of asphalt. However, it will adversely harden the ...
