The investigation of external aerodynamics of building of unusual architectural form

Abstract

The issues of buildings aerodynamics have always been considered rather important, and in some cases, crucial for the design of natural ventilation of buildings and smoke extraction systems. The applicable guidelines contain recommendations for regarding the nature of air can flow only along the sides of the building and on the roof. If the structure of the building differs from the rectangular, the nature of the distribution of excessive static and negative pressure zones is different. On the roofs of individual sections of buildings of an unusual configuration, excessive static pressure zone can be formed, which creates unfavorable conditions for the operation of natural ventilation and smoke exhaust systems. This paper presents the results of aerodynamic tests on a geometric model similar to a real residential complex of an unusual architectural form.
