Particle Entrainment in Convection Scenarios

Sustainability icon, disabled. A green leaf.
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.
