Wind tunnel experiments on wind turbine wakes in yaw: effects of inflow turbulence and shear
Wind Energy Science, 2018 . The wake characteristics behind a yawed model wind turbine exposed to different customized inflow conditions are investigated. Laser Doppler anemometry is used to measure the wake flow in two planes at x∕D = 3 and x∕D = 6, while the turbine yaw angle ...

A Massive Star is Born: How Feedback from Stellar Winds, Radiation Pressure, and Collimated Outflows Limits Accretion onto Massive Stars [PDF]
, 2022 Massive protostars attain high luminosities as they are actively accreting and the radiation pressure exerted on the gas in the star's atmosphere may launch isotropic high-velocity winds. These winds will collide with the surrounding gas producing shock-heated ($T\sim 10^7$ K) tenuous gas that adiabatically expands and pushes on the dense gas that may ...

Environmental Wind Tunnels [PDF]
, 2011 Wind tunnels have been used extensively in industry and research applications over the past 50 years. They vary greatly in scale and geometry, with some large enough to house and test small aircraft (see for example NASA, ATP facilities) and others are miniaturized flow generators used in the calibration of small sensors.

Design of a Freely Rotating Wind Tunnel Test Bench for Measurements of Dynamic Coefficients [PDF]
56th 3AF International Conference on Applied Aerodynamics,
Association A{\'e}ronautique et Astronautique de France (3AF), Mar 2022,
Toulouse, France, 2023 The needs to improve performances of artillery projectiles require accurate aerodynamic investigation methods. The aerodynamic design of a projectile usually starts from numerical analyses, mostly including semiempirical methods and/or Computational Fluid Dynamics (CFD), up to experimental techniques composed of wind-tunnel measurements or free-flight ...
