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 ...
Aerodynamic loads measurement of a sounding rocket vehicle tested in wind tunnel
(2009-12-01)
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 ...
AERODYNAMIC LOADS MEASUREMENT OF A SOUNDING ROCKET VEHICLE TESTED IN WIND TUNNEL
(Imeko, 2009-01-01)
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 ...
Flow in the wake of wind turbines : turbulence spectral snalysis by wind tunnel tests
(Science Publishing Group, 2016)
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 ...
Flight responses of Sitotroga cerealella (Lepidoptera: Gelechiidae) to corn kernel volatiles in a wind tunnel
(Arthropod-Plant Interactions, 2018)
On closed-section wind-tunnel aeroacoustic experiments with a two-dimensional lifting body
(2019-05-01)
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 ...
Concepção de um túnel aerodinâmico do tipo sucção com retorno aberto
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2014-02-13)
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 ...
RWEQ-Wind erosion predictions for variable soil roughness conditions
(Elsevier, 2016-03)
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 ...
Calibration uncertainty estimation for internal aerodynamic balance
(2008-12-01)
Aerodynamic balances are employed in wind tunnels to estimate the forces and moments acting on the model under test. This paper proposes a methodology for the assessment of uncertainty in the calibration of an internal ...
