Particle Entrainment in Convection Scenarios

In this study, dust entrainment and aerosol dynamics within the formation of dust devils are investigated numerically. Particles lying on the boundary are resolved in a periodic Rayleigh-Benard convection to investigate details of entrainment in scenarios analogous to the atmosphere. The details provided by the high-fidelity platform are powerful tools develop models of dust emission in the presence of no mean wind. A dependence of entrainment is found and documented for particle density, size along with the strength of stratification.

Improving the models of particle uplift by flow will help predict hazards such as dust storms and mitigate their detrimental effects.
