This paper presents an erosion interpretation of cohesive granular materials stressed by impinging jet based on the results a micromechanical simulation model. The numerical techniques are briefly described, relying two-dimensional Lattice Boltzmann Method coupled with Discrete Element Methods including simple model solid intergranular cohesion. These then used to perform parametric study plana...

When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...

The presence of CO2, sand, and water in oil gas reservoirs causes erosion–corrosion leading to material degradation pipelines fluid handling equipment that results increasing maintenance repair costs a decrease production. While the weight loss caused by is known depend on flow velocity, angle impact, sand loading size target properties, field operators often limit rate based critical corrosion...

The technology of submerged carbon powder injection with CO2 and O2 mixed gas (SCPI-COMG) is a new type technology. It can increase the molten bath content improve steel quality by injecting directly into gas. To optimize process parameters this novel technology, mechanism effect SCPI-COMG on EAF steelmaking were investigated in study. Based an induction furnace experiment, effects carburizatio...

The stationary hemispherical electrode under a submerged impinging jet is suggested as an experimental system that is amenable to in situ observation and has a uniform current distribution below the mass-transfer-limited value. The present work provides solutions for the steady-state boundary-layer hydrodynamics and convective diffusion. The observation of a boundary layer separation in the pre...

Previous studies have demonstrated the capability of superhydrophobic surfaces to produce slip flow and drag reduction, which properties hold considerable promise for a broad range of applications. However, in order to implement such surfaces for practical utilizations, environmental factors such as water movement over the surface must be observed and understood. In this work, experiments were ...
