Abstract We present observations of the Uranian outer ring system at near‐infrared and visible wavelengths. Observations with the Keck Telescope were taken in July‐August 2007 at 2.12 and 1.63 μm, when the ring plane was almost edge‐on (ring opening angle B=0.62 $B=0.62$–0.24° ${}^{\circ}$). These data showed, for the first time, the μ ring at infrared

Design of a 3.4‐MW wind turbine with integrated plasma actuator‐based load control
Historically, cost reduction in wind energy has been accomplished by increasing hub heights and rotor diameters to capture more energy per turbine. The growth in rotor and turbine costs with increasing turbine sizes is also driven by the additional ...

Aerodynamic performance and wake development of NACA 0018 airfoil with serrated gurney flaps
Improving the aerodynamic performance of the airfoil is important for optimising the rotor efficiency of the vertical axis wind turbines. As a simple passive control method, the Gurney flap is widely used to improve the aerodynamic performance of ...

This study presents a cost‐conscious GT3 aerodynamic‐optimisation workflow combining 3D scanning, full‐vehicle GPU‐accelerated lattice Boltzmann method simulations, and component wind‐tunnel tests. Its contribution is a transparent scan‐to‐decision process rather than a new LBM formulation.

Decision‐making for wāhine Māori facing breast cancer surgery: a qualitative study
ABSTRACT Wāhine Māori (women/females) are disproportionally affected by breast cancer in Aotearoa New Zealand. Following a breast cancer diagnosis, wāhine must make important surgical decisions while navigating a Westernised health system that can be dismissive of Māori views of health and tikanga (customary practices).

Effect of Gurney Flaps on Non-Planar Wings at Low Reynolds Number
The effect of spanwise wing non-planarity, employed in conjunction with a Gurney flap, is presented. Testing was undertaken in a low-speed wind tunnel using a rectangular wing with an aspect ratio of three. The outer one-third of the wing was non-planar,

Effect of Gurney Flap Geometry on a S809 Airfoil
In this paper, the effect of Gurney flap shapes on wind turbine blade airfoil S809 has been studied by numerical simulation. First, the O-type grid is used in the numerical simulation. By comparing with experimental data, such as the lift force, the drag

Aerodynamics and aeroacoustics of flap side-edges [PDF]
An experimental and computational investigation was carried out to determine the aerodynamics and aeroacoustics of a flap side-edge. A porous side-edge treatment was applied to the flap side-edge in an attempt to reduce airframe noise. Measurements taken
