A model for the resuspension of a monolayer of particles deposited on a flat surface is developed based on a Monte Carlo simulation of the phenomenon. Particles deposited on the surface are attached to it through an adhesion ...

In this study we present a simulation model based on a Monte Carlo method to describe the resuspension of particles deposited on a flat surface due to air flow. Particles are attached to the surface through an adhesion ...

In particle resuspension phenomena, experimental and simulation evidence demonstrate that, as the acceleration increases, higher air velocities are needed for particle re-entrainment, and the process requires less time to ...

On 14 December 2013, the Cooperative Institute for Meteorological Satellite Studies (United States) reported a volcanic ash cloud apparently emitted by the Puyehue Cordón Caulle Volcanic Complex (Chile) and indicated its ...

Atmospheric dispersion of volcanic ash from explosive eruptions or from subsequent fallout deposit resuspension causes a range of impacts and disruptions on human activities and ecosystems. The April-May 2015 Calbuco ...

The rates of sedimentation and resuspension of organic carbon and total nitrogen were measured in earthen fishponds, based on nutrient input, water quality parameters and fish size and biomass. Material collected in ...

he vibration of dusty surfaces inevitably causes re-entrainment of particles into the atmosphere. Given that movement of mineral dust particles deposited on a surface begins at a critical frequency (fc) and amplitude, an ...

Volcanic fallout deposits from the June 2011 Cordón Caulle eruption on central Patagonia were remobilized in several occasions months after their emplacement. In particular, during 14-18 October 2011, an intense outbreak ...

We discuss two typical problems involved in particle resuspension phenomena. First, we analyze the onset of movement of a grain deposited on a surface prior to its possible resuspension. In this case, we look for the ...
