TL;DR: In this paper, the authors examined the prediction accuracy of pollutant dispersion within an urban street canyon of width to height ratio W/H=1 using two steady-state Reynolds-averaged Navier-Stokes (RANS) turbulence closure models, the standard k-e and Reynolds Stress Model (RSM), and Large Eddy Simulation (LES) coupled with the advection-diffusion method for species transport.

TL;DR: The investigations carried out in this work allowed us to set up an appropriate CFD modelling methodology for the study of the aerodynamic effects of tree planting in street canyons, and the results obtained can be used by city planners for the design of tree plantings in the urban environment with regard to air quality issues.

TL;DR: In this article, the authors apply efficiency concepts originally developed for indoor environments to the study of pollutant concentration distribution within urban-like geometries, and apply the term venti...

TL;DR: In this article, the effect of street canyons of different aspect ratios and various obstacle array configurations consisting of cubical buildings is investigated with the standard k- e turbulence model and the advection-diffusion (AD) method for the CFD simulations.

TL;DR: In this article, the aerodynamic effects of trees on local scale flow and pollutant concentration in idealized street canyon configurations by means of laboratory experiments and Computational Fluid Dynamics (CFD).
