Selection criteria of optimal conditions for supersonic tests in a blowdown wind tunnel [PDF]
Scientific Technical Review, 2016 A natural desire of a wind tunnel test engineer is to plan and perform a test that will resemble the actual flight conditions as closely as possible. Geometric similarity and identical flight and wind tunnel Mach numbers are the primary requirements and ...

Development of wind tunnel for laboratory wind turbine testing
2011 North American Power Symposium, 2011 This paper presents the development of a wind tunnel that will be used for wind turbine testing in a controlled environment. The prototype is designed to be able to provide wind speeds of up to 20 m/s (∼43mph) depending on the cross sectional area of the tunnel chamber.

The Update of an Aerodynamic Wind-Tunnel for Aeroacoustics Testing
Journal of Aerospace Technology and Management, 2014 This paper describes the update and characterization of a previously pure aerodynamics wind-tunnel into a facility able to simultaneously execute aerodynamics and aeroacoustics testing. It is demonstrated that the application of high-performance acoustic materials on strategic positions of the wind-tunnel circuit and punctual actions can substantially ...

Wind Turbine Wake Modeling in Accelerating Wind Field: A Preliminary Study on a Two-Dimensional Hill
Fluids, 2019 Complex terrain can influence wind turbine wakes and wind speed profiles in a wind farm. Consequently, predicting the performance of wind turbines and energy production over complex terrain is more difficult than it is over flat terrain.

In wind tunnel the reproduction of vortex shedding behind circular cylinders at high Reynolds number regimes is incomplete [PDF]
arXiv, 2023 Wind tunnel tests of 2D rough cylinders are presented. The goal is to simulate the alternate vortex shedding in flow regimes encountered in wind engineering applications, where the full scale Reynolds number is larger than the one that can be reproduced in wind tunnel with small scaled models.
