In this study, spectra obtained from wind tunnel data are compared with a model that describes observed atmospheric neutral spectra. The investigation points out that there is a good conformity between both spectra for ...

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 ...

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 ...

The present contribution reports on the status of the STROMA experiment. As a novelty a new experimental setup in a wind tunnel allows to simulate different stability regimes with vertical heat flux in either direction. ...

The soil surface roughness is a main factor in all wind erosion prediction models, including the Revised Wind Erosion Equation (RWEQ). The objective of this study was to test the erodibility of two typical soils of the ...

Broiler production in Brazil has turned into a very competitive activity in the late years. Constant innovation leads to higher productivity maintaining the same cost of production, which is a desirable situation. Lately ...

The PM10 emission efficiency of soils has been determined through different methods. Although these methods imply important physical differences, their outputs have never been compared. In the present study the PM10 emission ...

Slat noise experiments are sometimes performed to provide data for the validation of numerical procedures. Under such circumstances, closed-section wind-tunnels, in contrast with open-section ones, offer well-defined ...
