Multi‐Rotor Systems: Can They Increase Economy‐Wide Benefits Compared to Traditional Designs?
ABSTRACT This short communication reports on the economic consequences of increasing the market share of potentially lower‐cost offshore wind designs. We use data on the projected levelised cost of energy (LCOE) for traditional horizontal axis wind turbine (HAWT) designs compared with an illustrative multi‐rotor system which could have lower costs ...

Influence of pitching on performance of VAWTs [PDF]
AbstractSelf‐ starting is the major obstacle to be overcome for successful design of a vertical axis wind turbine (VAWT). In the past has been suggested that pitching the turbine blades such that pitch angle is not 90 degrees allows for self‐starting.

ABSTRACT Vertical‐axis wind turbines (VAWTs) operate in the atmospheric boundary layer and are frequently subjected to turbulent flow. The objective of this study is to investigate the effect of free‐stream turbulence on the power performance and wake characteristics of a pair of counter‐rotating VAWTs.

The Past, Present and Future of Structural Health Monitoring: An Overview of Three Ages
ABSTRACT This paper presents an overview of the discipline of structural health monitoring (SHM), organised in terms of three proposed ages. The first age is delineated by the prehistory of SHM and the period where nondestructing testing methods evolved into an organised set of principles built upon physics‐based models; this age ended when the model ...
