Full-scale downburst damage versus boundary layer wind tunnel pressures : a survey analysis
(Northeastern University, 2016-06-11)
On the night of January 29, 2016 a thunderstorm event was registered in Porto Alegre, Brazil. The winds
caused damage throughout the majority of the city, leaving more than 220,000 houses without electricity and
thousands ...

Control of Reynolds number in a high speed wind tunnel
(Departamento de Ciência e Tecnologia Aeroespacial, 2009)
A conceptual control model for the Reynolds number test based on isentropic relations was established for the supersonic wind tunnel. Comparison of the system response of the model simulation and the actual wind tunnel ...
Multisatellite Analysis of Plasma Pressure in the Inner Magnetosphere During the 1 June 2013 Geomagnetic Storm
(Blackwell Publishing Ltd, 2019)
Using data from Defense Meteorological Satellite Program 16–18, National Oceanic and Atmospheric Administration 15–19, and METOP 1–2 satellites, we reconstructed for the first time a two-dimensional statistical distribution ...
Buckling estimates for oil storage tanks: Effect of simplified modeling of the roof and wind girder
(Elsevier, 2015-06)
Oil storage tanks are short cylindrical shells fabricated with an external fixed roof or floating roof on the inside. Some features of the structure tend to be simplified in practice and research in order to perform stability ...
Optimization of RANS turbulence models using genetic algorithms to improve the prediction of wind pressure coefficients on low-rise buildings
(Elsevier Science, 2019-10)
Being associated with natural ventilation, the pressure distribution on surfaces is relevant for energy consumption, thermal comfort, and air quality in buildings. The aim of this work is to present a simulation-based ...
Mean loads on vaulted canopy roofs
(Elsevier Science, 2013-08)
The vaulted canopy roof (VCR) is a widespread structure used in vast areas of South America, especially in parts of Argentina, Brazil and Paraguay. Information about the aerodynamics of VCRs is scarce in the literature, ...
Wind buckling of tanks with conical roof considering shielding by another tank
(Elsevier, 2014-06)
Oil storage tanks are usually arranged in groups in tank farms, and this configuration may affect their buckling and postbuckling strength under wind loads. The assessment of wind action on tank structures is performed in ...
Theoretical and Experimental Analysis of Aerodynamic Noise in Small Wind Turbines
This paper presents an analysis of sound pressure levels through theoretical modeling and experimental validation in a 1 kW small wind turbine. The models used in the theoretical analysis are BPM (Brooks, Pope, and Marcolini) ...
Análise comparativa entre respostas de torre de transmissão sujeita a carregamentos obtidos através do método do vento sintético e da norma NBR 6123/88
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Civil, 2015-04-24)
There are several procedures to determine the wind loadings. The Brazilian code NBR 6123/88 can be used to determine these loadings and the internal forces for structural design. However, there are non-normative procedures ...
