Velocity Slip in a Deep-sea Slurry Pump and Its Effect on Particle Transportation [PDF]
Journal of Applied Fluid Mechanics, 2023 The slurry pump, which forms the core equipment of the deep-sea mining (DSM) system, provides lifting power for the ore from the seabed to the sea level, which is crucial for the safety of coarse ore particle transportation.

ANALISIS GROUND VIBRATION DENGAN METODE PEAK PARTICLE VELOCITY (PPV)
Faktor Exacta, 2021 <p><em>Measurement of Peak Particle Velocity (PPV) mm / sec in the Sabo dam construction project was carried out using seismic accelerometers. This study is to determine the value of PPV produced by construction equipment and then compared with the BS 6472-2: 2008 standard. The measurement method is carried out based on the applicable rules.

Journal of Marine Science and Engineering, 2021 The water particle velocity of the wave peaks is closely related to the wave load borne by offshore structures. It is of great value for marine disaster prevention to study the water particle velocity of nonlinear extreme waves represented by Freak waves.

Rock blasting — peak particle velocity against distance [PDF]
Proceedings of the Ninth Symposium on Field Measurements in Geomechanics, 2015 The potential damage which could be induced by blasting in rock is normally evaluated with reference to the peak particle velocity (PPV). It is well-known that closer distances lead to higher PPV values. In some cases, due to muck handling logistics, the ramps forming the access result in different elevations across the different parts of a very deep ...

Computation of Surface Wave Parameters and Peak Particle Velocity
Journal of Structural Technology, 2023 In recent times, the rise in terrorist activities has underscored the critical need for designing structures with blast resistance capabilities. However, many Indian codes currently in place do not adequately address the issue of blast loads. This knowledge gap poses a significant challenge to engineers who must ensure the safety and security of ...

Predicting the peak particle velocity from rock blasting operations using Bayesian approach [PDF]
Acta Geophysica, 2022 AbstractMeasuring the blast-induced ground vibration at blasting sites is very important, to plan and avoid adverse effects of blasting in terms of the peak particle velocity (PPV). However, the measurement of PPV often requires time, cost, and logistic commitment, which may not be economical for small-scale mining operations.

Directed transport of a deformable particle in confined periodic structures
New Journal of Physics, 2022 Directed transport of a deformable particle is numerically investigated in a two-dimensional periodic channel. Unlike the rigid particle, the deformable particle can pass through the channel bottleneck that is significantly smaller than the particle size.
