The monitoring of the frequency, intensity/magnitude and dynamics of explosive events at volcanoes in a state of unrest is key to surveying and forecasting their activity. Thermal and visual video observations of eruptive phenomena, and their correla

We report on direct measurements of the basal force components for granular material flowing down a smooth incline. We investigate granular flows for a large range of inclination angles from teta=13.4{\deg} to 83.6{\deg} and various gate opening of t

Lava dome collapses are a major threat to the population living near such volcanoes. However, it is not possible to forecast collapses reliably because the mechanisms are not clearly understood, due partly to the lack of continuous observations of su

MEASUREMENT OF DARCY AND FORCHHEIMER COEFFICIENTS FOR SILICA SAND BEADS

Autor: Thierry Latchimy, David Rochette, Gérard Velleaud, William Bussiere, Pascal André

Publikováno v: High Temperature Material Processes (An International Quarterly of High-Technology Plasma Processes). 10:55-78

High Breaking Capacity fuses are widely used to withdraw the energy brought by an electric fault current. One of the main constituent elements of a HBC fuse is the arc quenching material, silica sand in our case. During the arc quenching by the fuse,
