Analytical and practical analysis of frictional-kinetic model for dense and dilute gas-solid flows ET2013-007/C2016-160 | 2016In granular flows, when the solid volume fraction is large, the dynamic behaviour of particles becomes controlled by frictional effects. Theoretically these effects can not be taken into account in an Eulerian approach, based on the kinetic theory…

Three-dimensional simulation of aerosolization of powders when transferring materials in powder form ET2013-007 | 2013Almost all industrial sectors are concerned by production or handling of materials in powder form: agri-food, metallurgy, pharmacy, milling, baking, fine chemicals, mining, etc. When such materials in powder form are handled or bagged, a fraction…

Numerical analysis of dust emission by powder discharge and jet expansion ET2013-007/C2014-108 | 2014The paper deals with the Euler-Euler numerical simulation of an experimental study (Ansart et al., 2009[1]) of freely falling granular jetfor investigating the dispersion of dust. The configuration is a bunker,where quasi-static particulate flow…

Improving the scavenging kernel of aerosol particles by small water drops EL2014-015/C2015-058 | 2015Scavenging aerosol particles by means of water sprays is an efficient way of removing hazardous dust from the atmosphere. Starting from the work of Wang et al. (1978), we propose to extend its formulation of a theoretical scavenging kernel to particles…

Aerosol scavenging by drops : deriving a collection kernel from microphysical modelling EL2014-015/C2016-007 | 2016Scavenging aerosol particles by droplets is an efficient way of removing solid particles from gases. Despite its interest for both industrial applications and occupational health, predicting realistic removal rates by means of a simple collection…
