Aerosol dispersion: Modelling scalar transport in the atmosphere using LES-LBM

Transport of small sized droplets/particles is of paramount importance to describe many industrial and natural systems, from combustion engines, to weather dynamics, the dispersion of pollutants and contaminants or the performance of medical devices and personal protective equipment. Modelling tools to describe small scale systems involve complex and computationally expensive tools able describe the smallest scales of a turbulent multiphase flow with a big resolution. The complexity of solving turbulence at such small scales and its effect individual particles makes the application of particle resolved methods impossible over large volumes, which limits the use in industry, environment and natural systems. In this project you will explore solutions to this issue developing large-eddy simulations (LES) formulations that tackle the dynamics of large-scale flows such as the atmospheric boundary layers, in conjunction with lattice Boltzmann method (LBM) to describe the transport of aerosols (small sized droplets and particles whose motion is dominated by a surrounding fluid). Doing so you will be able to tackle the main driving factors of the transport of aerosols and predict how contaminants, and pollutants disperse over a large space to inform decision making in areas as diverse as healthcare, industrial design, analysis of ecosystems and climate change.
