Direct numerical simulations of interface-resolved sediment transport in horizontal open-channel flow are currently being performed on the XC-4000. The channel bottom boundary is roughened with a fixed layer of spheres and about 9000 particles are allowed to move within the computational domain. The density ratio of the solid and fluid phase is 1.7 and the bulk Reynolds number of the flow is 28...

Abstract In Euler–Euler particle-laden flow models, the interphase coupling terms might include, in addition to drag force, effects of fluid pressure interaction with particles and volumetric displacement phase due presence particles. This paper presents an analytical study on these for laminar, one-dimensional, steady, inviscid flow. The force is represented by a linear Stokes formula that val...

In this paper we demonstrate a new type of quantum phase coherence (QPC), which is generated by the two-body interaction. This conclusion is based on quantum master equation analysis for the full counting statistics of electron transport through two parallel quantum-dots with antiparallel magnetic fluxes in order to eliminate the Aharonov-Bohm interference of either single-particle or non-inter...

The two-phase gas-liquid flow properties of high-velocity open channel flows were studied experimentally in a large-size channel. The physical facility was equipped with a succession of triangular cavities associated with some strong interactions between air entrainment and flow turbulence. Detailed air-water flow measurements were collected with intrusive phase-detection probes for several flo...

In fluid-structure interactions and fluid simulations, like incompressible two-phase flows involving high viscosity and density ratios, interface capturing and tracking is considered as a very challenging problem and has a strong impact on industrial applications. Usually, an adaptive grid is used to resolve the problem as well as to track the interface. In this paper, we describe an adaptive s...

[1] Tide-induced variations in subsurface air pressure, mainly between 1.0 to 2.0 kPa, are observed in coastal areas in Hong Kong. A two-dimensional model which couples the two-phase air-water flow in unsaturated and saturated zones successfully reproduces the observed air pressure under no rain conditions. The simulation reveals that significant increases in air pressure depend on the tidal ra...
