Computer simulation of the aeration mode of residential development for ventilation and wind protection

The creation of favorable conditions for the population to live in residential buildings is one of the most important goals of urban planning, and it directly depends on the aeration mode of the development area. The article presents a description of the methodology for performing numerical simulation of wind impact on a model of residential development for the reason of wind protection of the territory, its airing and creating comfortable and safe living arrangements for the population, according to a similar semi-natural experiment. The problem of air-flow conditions for residential buildings is solved using finite element analysis in the ANSYS CFX package. The results are compared with the data obtained in an aerodynamic tube during an experiment with a similar building model. The investigated patterns of wind flow around a group of buildings can be useful for assessing the comfort of pedestrian zones when developing architectural and planning concepts for street blocks and planning the construction of buildings within existing blocks.
