Turbulence now bad wind farms as it decreases the energy they capture

The Hindu  

Published : Oct 06, 2022 09:40 IST AN improved understanding of interactions between wind farms and the local atmosphere can help optimise wind farm designs for greater energy output. Supercomputer simulations carried out by scientists, led by Anja Stieren, of the University of Twente in The Netherlands, have shown that negative shear “baroclinicity”, an atmospheric condition, can reduce wind velocity and enhance turbulence above wind farms, thus decreasing the energy the farms can capture. The results add a surprising new nuance to physicists’ current understanding of the ways in which turbulence can boost wind farms yields. The results of the present simulations work, which were published in the latest issue of Physical Review X Energy, however, have shown that negative shear baroclinicity-generated turbulence creates an upward flux that diverts wind energy away from the farm.

‘More efficient’ vertical turbines should replace traditional design on wind farms, researchers say

The Independent  

New research suggests the now-familiar sight of three-blade wind turbines should be replaced in future with more compact and efficient vertical turbines. The researchers used almost 12,000 hours of computer simulations to show that wind farms could perform more efficiently by substituting the traditional propellor type turbines for vertical axis turbines. They said the research demonstrates for the first time …
