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 interaction between the incident wind and wind turbines in a wind farm causes mean velocity deficit and increased levels of turbulence in the wake. The turbulent flow is characterized by the superposition of wind turbine ...

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 ...

In wind tunnels, aerospace vehicle models are tested in order to analyze their performance in real flight situations. The forces and moments exerted by the airflow on the surface of the test article are measured using ...

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 ...

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 ...

This Final Course Assignment shows the design, construction and preliminary tests of a suction type wind tunnel with open return used for teaching and research in engineering courses. From a morphologic point of view, the ...
