Shock waves and granular vacua are important phenomena for studying the behavior of materials due to dramatic change in flow properties across shock wave particle-free feature at boundary vacuum. In this paper, we use experiment numerical simulation study free-surface past a cylindrical obstacle an inclined chute, where time-dependent development impacting is analyzed both microscopic macroscop...

When a granular mixture involving grains of different sizes is shaken, sheared, mixed, or left to flow, grains tend to separate by sizes in a process known as size segregation. In this study, we explore the size segregation mechanism in granular chute flows in terms of the pressure distribution and granular microstructure. Therefore, two-dimensional discrete numerical simulations of bidisperse ...

A major factor affecting fresh pork quality is the implementation of management technologies that improve swine movement at the time of loading. Two experiments were conducted to evaluate the effects of the loading system at the farm (traditional chute T vs. prototype loading gantry P) on the quality attributes of fresh pork loins. Two marketing groups were utilised. Experiment 1 used 100 pig l...

This paper contains a short description of the experimental Lautaret site dedicated to avalanche dynamic studies. Since the seventies, many experimental campaigns allowed measuring different avalanche parameters such as velocity, height and pressure. Technical development have been also carried in this site and are presented here. More recently, a chute for physical modelling of avalanche motio...
