Large-eddy simulation of aerosol concentrations in a realistic urban environment: Model validation and transport mechanism

PALM model system demonstrates good performance compared to portable instruments. Pollutant distributions have greater complexity than seen in idealized domains. Different aerosol …

Large-eddy simulation of the optimal street-tree layout for pedestrian-level aerosol particle concentrations – A case study from a city-boulevard

The spatial variability of air pollutant concentrations was experimentally evaluated using observations from a mobile laboratory and a drone. We observed that both mean flow and …

Sensitivity of spatial aerosol particle distributions to the boundary conditions in the PALM model system 6.0

High-resolution modelling is needed to solve the aerosol concentrations in a complex urban area. Here, the performance of an aerosol module within the PALM model to simulate the …

Large-eddy simulation of the optimal street-tree layout for pedestrian-level aerosol particle concentrations – A case study from a city-boulevard

Street trees weaken pollutant dispersion but also enhance removal by dry deposition. Aerosol dispersion and size-specific dry deposition are studied within urban LES. Generally …
