Abstract

The atmospheric boundary wind tunnel constitutes an important tool to study of the action of the wind on the most diverse types of civil structures. The equipment can be used to develop tests inside small-scale models, in order to understand how they will be affected by the air movement, allowing the analysis of several variables related natural ventilation in buildings, such as speed, pressure, temperature and pressure coefficient, which justifies its application in this research area. The objective of this research is to compare tests carried out in two atmospheric boundary layer wind tunnels: the wind tunnel located in the Institute for Technological Research of the state of Sao Paulo (IPT) and the wind tunnel located in the School of Civil Engineering, Architecture and Urban Desing of the University of Campinas (FEC-UNICAMP), with the purpose of generating wind pressure coefficients for high-rise building with balconies. Specific objectives are to assist the development of a master's degree research project, currently in progress. To generate the wind pressure coefficients, a small scale physical model will be built and quantitative and qualitative airflow analyzes will be developed. In order to verify the validity and accuracy of the results obtained in the wind tunnel of FEC-UNICAMP, the results of the tests carried out in the wind tunnel of IPT will be used as a reference, checking whether there is an agreement between both. Thus, by relating the results obtained in both wind tunnels, it will be possible to verify its coherence with standards, adding value to the already existing results in the specific literature of this area, and also expanding the knowledge related to the natural ventilation of buildings provided with balconies.
