Lattice Boltzmann Method-Based Simulations of Pollutant Dispersion and Urban Physics

Mesocale atmospheric flows that develop in the boundary layer or microscale urban areas are challenging to predict, especially due multiscale interactions, multiphysical couplings, land and surface thermal geometrical properties turbulence. However, these different can indirectly directly affect exposure of people deteriorated air quality environment, as well structural energy loads buildings. Therefore, ability accurately predict interacting physical processes determining is primary importance. To this end, alternative approaches based on lattice Boltzmann method (LBM) wall model large eddy simulations (WMLESs) appear particularly interesting they provide a suitable framework efficient numerical methods for prediction complex smaller scale flows. In particular, article summarizes recent developments studies performed using hybrid recursive regularized collision simulation or/and coupled turbulent Different applications meteorological humid flows, pollutant dispersion, pedestrian wind comfort pressure distribution buildings including uncertainty quantification reviewed. For applications, accuracy developed approach was assessed by comparison with experimental and/or reference data, showing state art performance. Ongoing focus now validation indoor environmental conditions mixing dispersion types rooms equipped heat, ventilation conditioning systems.
