Abstract

The article presents an overview of numerical solutions of computational fluid dynamics in the field of urban planning. The study is devoted to new solutions to maintain a comfortable microclimate in urban spaces in hot climates. Such territories require comprehensive urban planning and scientifically based environmental assessment. Numerical modelling in the Ansys Fluent software package is considered using the example of the influence of turbulence models on airflow parameters near a building site with and without green spaces. The article analyses the temperature and aeration conditions of the adjacent car park in three options: open (without landscaping); fenced with bushes; fenced with bushes with a canopy made of lightweight construction, without internal partitions, on the territory of an existing residential development, consisting of a group of 16-storey buildings in the new modern multi-storey micro district Karasuv in Samarkand (Republic of Uzbekistan). The performed CFD analysis provided an opportunity to determine the most effective localization of green spaces due to the consideration of their different combinations. The use of the CFD method when solving a problem makes it possible to optimize the period of pre-design analysis. The resulting numerical model of a house parking lot can be used to assess the impact of wind conditions and temperature regulation using a system of green spaces that provide stable and balanced heat input to the environment.
