The high-speed flow of sand-carrying fracturing fluid through tee junctions causes severe
erosion and affects the safety of the fracturing operation. This study improves the traditional …

High-concentration solid-liquid two-phase flow causes particle erosion or accumulation at
the sudden change positions of flow channels, resulting in pipe leakage and tool failure. In …

This paper presents a detailed experimental and numerical analysis of free-falling particle
streams impacting a 45° inclined surface of differing materials. The particles used in this …

Highly resolved numerical simulations by the immersed boundary method are used to study
neutrally buoyant spherical particle motion when carried by fluid approaching a wall. The …

The gas production of offshore gas well testing is generally large, and sand production is
inevitable, which will cause erosion risk of testing pipeline. In this research, surface process …

In this paper, we study the dynamics of one-dimensional chains composed of elastoplastic
beads. Three uniform chains, which were experimentally studied in the existing literature …

Particle impact is technologically important and can cause significant damage to a surface.
Detecting the approach and impact of a particle would give key information on the process …

A model is presented for the bouncing dynamics of a fluid-immersed sphere impacting
normally a textured wall with micropillars. By taking into account the hydrodynamic and …

Oscillatory motions of charged particles inside a liquid medium have been explored under
the influence of an electric field emulating field-induced particle-laden fluid flows. The …

Systematic experiments were conducted to elucidate how the dynamics of a fully immersed
spherical pendulum in a normal approach to a wall may change with the presence of a third …
