Atmospheric processes in elements of urban construction

The authors demonstrate the efficiency and accuracy of the developed hydrodynamic model of the atmosphere, turbulent closure model, approximation methods for first- and second-order derivatives on an irregular grid, and the absolutely stable difference scheme based on the solution of applied problems. The results of mathematical modeling of aerodynamics of street canyons are compared with available theoretical and experimental data. Influence of street canyon length and house height on air flow characteristics in urban areas is investigated. It is shown that changes in the configuration of urban area lead not only to quantitative but also to a significant qualitative variation in air flow pattern and velocity. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
