Mathematical Modeling of Air Flow Dynamics for Assessing the Comfort of Pedestrian Zones in Urban Development
The purpose of the research work is to perform mathematical modeling of aerodynamic processes that occur when the designed buildings flow around in an urban environment to assess the comfort of pedestrian zones. To achieve this goal, the following tasks were set: to study the regulatory documents in the field of assessing the wind comfort of the territory; to collect climate data and analyze the wind climate of the area under consideration; to create a solid geometry model of the designed, surrounding buildings and terrain in Revit; to carry out mathematical modeling of the dynamics of air flows in RWIND Simulation; analyze the results. The hypothesis of the study is that there are air corridors in the planned development, the duration of the occurrence of critical wind speeds in which does not comply with regulatory documents in the field of assessing wind comfort. The methods of analysis, modeling and measurement were used as research methods. As a result of the analysis of data obtained using CFD-modeling, it was identified that in the northern, northeastern, southern and southwestern wind directions an air corridor was formed, the wind speed in which reached more than 5 m/s, which is uncomfortable for a long stay in this building area. Since the object is under construction and it is impossible to change the location of the houses, measures have been developed to improve the comfort of the pedestrian zones of the planned development.
