Direct Numerical Simulation of Microparticle Motion in Channel Flow with Thermophoresis
Publisher: American Society of Civil Engineers
Abstract: The motion of microparticles in a vertical flow channel driven by drag and thermophoretic forces was simulated using the direct numerical simulation method with the particles tracked using the Lagrangian method. The particle ...
Numerical Procedure for Simulating the Two-Phase Flow in Unsaturated Soils with Hydraulic Hysteresis

Bearing Capacity of Two-dimensional Reinforced Composite Foundation
Publisher: American Society of Civil Engineers
Abstract: The bearing performance of both vertically and horizontally reinforced composite foundation formed by horizontal reinforcement settled on top of granular piles, which can restrict the failure of granular piles, was studied. ...
Analytical Model of Soil-Water Characteristics Considering the Effect of Air Entrapment
Publisher: American Society of Civil Engineers
Abstract: Based on experimental data and the flow property analysis of the drying-wetting process of fluids under a microscope, a theoretical model is developed to consider the effect of air entrapment in the soil-water retention ...
Soil Shrinkage: Underlying Mechanisms Revealed by Intergranular Stress
Publisher: ASCE
Abstract: When drying from a fully saturated state, soil transits from saturation to unsaturation, activating the effects of capillarity, adsorption, and osmosis. Traditionally, these effects have been elusive in modeling soil ...
Bond–Slip Behavior of Concrete Pile–Cemented Soil Interface Considering Thermal–Temporal Effect: Experimental Study and Constitutive Modeling Based on Disturbed State Concept
Publisher: American Society of Civil Engineers
Abstract: The bond–slip behavior of concrete pile–cemented soil interface is crucial for load transfer analysis of stiffened deep cement mixing piles, which is greatly influenced by ground temperature and age during long-term curing. ...
