Modeling of the deep granular bed filtration of nanoparticles ET2013-004/C2016-100 | 2016

In the case of industrial ultrafine particles filtration by a granular bed, the calculation of the efficiency and the pressure drop evolution is a key step towards the installation design. In this goal, a clogging model based on the expression…
Aerosol scavenging by drops : deriving a collection kernel from microphysical modelling EL2014-015/C2016-007 | 2016

Scavenging 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…
Improvement of granular bed filtration performances ET2013-004/C2015-131 | 2015

Some authors highlighted that during the filtration of ultrafine particles, the deposit is essentially located in the first layers of the granular bed. Thus, only a small depth is useful thereby reducing both the operation time between each unclogging…
Modelling the removal rate of airborne dust by sprays: importance of a realistic scavenging kernel EL2014-015/C2016-015 | 2016

Indoor air quality can be strongly affected by high aerosol particles concentration. When ventilation is not possible, aerosol scavenging by water sprays can be applied to protect workers. But, despite its interest for both industrial applications…
Modeling granular beds clogging by nanoparticles ET2013-004/C2015-128 | 2015

In the case of industrial ultrafine particles filtration by a granular bed, the calculation of the efficiency and the pressure drop evolution is a key step towards the installation design. In this goal, a clogging model based on the expression…
Modeling strategy for the determination of photocatalytic reaction kinetics in supported catalyst reactors ET2012-002/C2014-018 | 2014

This study proposes a modeling strategy for the determination of photocatalytic reaction kinetics in supported reactors. The packed bed studied is designed to degrade formaldehyde and is composed of TiO2-coated Raschig rings. The original…
Visualization of nanoparticles deposits onto spherical collectors ET2013-004/C2016-101 | 2016

In order to develop predictive models dealing with the granular beds clogging by nanoparticles, the deposit morphology on the collectors is a key information. Therefore, we decided to observe this type of deposit both on a magnetic beads line…
Modeling aerosol scavenging by drops: from microphysical CFD simulations to a global collection kernel EL2014-015/C2016-095 | 2016

Scavenging aerosol particles by droplets is an efficient way of removing hazardous particles from gases. Therefore, predicting removal rates by means of a realistic collection kernel is a purpose in several research fields like environment…
Determination of airborne nanoparticle mass concentration from number concentration using their effective density - Application to ELPI data ET2013-004/C2014-017 | 2014

Nanoparticles are generated by numerous industrial processes like arc welding, thermal metal spraying, combustions. Effective density (e) is among the key characteristics of airborne nanoparticles due to its role in particle deposition in…
Respiratory protection against nanoparticles: elements for a better respirators selection guidance ET2013-006/C2016-122 | 2016

The performance of different types of Respiratory Protective Device (RPD) against
nanoparticles are experimentally determined on a dedicated test bench. The influences of the fit of the facepiece, the breathing rate and the particle size are…
