Predicting the peak particle velocity from rock blasting operations using Bayesian approach [PDF]
, 2022 Measuring 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).

Particle image velocimetry studies of bubble growth and detachment by high speed photography [PDF]
, 1997 An understanding of bubble flows is important in the design of process equipment, particularly in the chemical and power industries. In vapour-liquid processes the mass and heat transfer between the phases is dominated by the liquid-vapour interface and ...

Numerical investigation of particle velocity distributions in aeolian sand transport [PDF]
, 2010 Particle velocity distribution in a blowing sand cloud is a reflection of saltation movement of many particles. Numerical analysis is performed for particle velocity distribution with a discrete particle model.

The influence of toughening-particles in CFRPs on low velocity impact damage resistance performance [PDF]
, 2014 The role of particle-toughening for increasing impact damage resistance in carbon fibre reinforced polymer (CFRP) composites was investigated. Five carbon fibre reinforced systems consisting of four particle-toughened matrices and one system containing ...
