Abstract: The paper reveals the capabilities of SigmaFlow CFD code to predict wind conditions in terms of pedestrian comfort as illustrated by a model problem. The proposed numerical model was verified by comparing with experimental data. A group of buildings consisting of low-rise buildings and a high-rise building was considered. A comparative analysis of five computational variants with different grid saturation was performed. The results of mathematical modeling allow observing the vortex flow structure that is gene… Show more

The paper presents the results of a numerical forecast of the pedestrian comfort level in the territory of urban development. The research uses the microscale numerical model of the atmosphere in the urban environment, into which the equations of temperature and seasonal indices are integrated. These equations are used to simulate and analyse pedestrian comfort conditions. The paper presents the results of the proposed model approbation in the real environment of the residential neighbourhoods of Krasnoyarsk city. External conditions, typical for summer and winter seasons, were simulated. The results produced are presented as distribution fields of the considered indices. During the analysis, comfortable/discomfort areas for humans staying in the environment of studied urban development were revealed.

The article considers the influence of the relief, river, and urban development on the formation of vortex structures in the atmosphere and the spread of pollutants in the city of Krasnoyarsk in winter. The weak influence of urban development on the appearance of large vortex structures over the river is shown. However, in the ground layer, it significantly changes the flow pattern and determines the character of the distribution of pollutants.

This paper presents the results of working out the methodology for conducting experimental studies of the flow around the objects modeling the urban environmental conditions. The experiments were conducted in the wind tunnel of the Siberian Federal University. Two objects of different heights imitating buildings were considered the models. Special attention was paid to the study of the flow pattern at the tandem arrangement of model buildings. Visualizing the flow, the low-velocity and high-velocity zones, as well as recirculation areas were identified. At that, these zones had their peculiarities in terms of the direction of flow twisting behind each object. The study allowed revealing that the vortices separating from the edges of the studied objects play a special role in the flow formation.
