AERODYNAMICS EVALUATION OF HIGH-RISE BUILDINGS

Abstract

Due to the increasing population density in metropolitan areas, architects have focused on high rise building designs that combine architectural considerations with functional requirements. The optimal design of the building shape in the case of wind interaction can be determined using the CFD evaluation method. This study uses the CFD analysis method to analyse the airflow around a new high-rise building. The first part of the paper presents a comprehensive overview of the state of the art regarding the building shapes used and the main simulation method. In the second part of the paper, the buildings model is created using dedicated CAD software. Two simulation cases are being prepared with two wind flow situations at 15 m/s velocity. In the third part of the paper, the results of CFD analysis of the buildings group model are presented. The conclusions of this evaluation are shown in the last part of the paper.
