Flows through a vertical axis wind turbine (VAWT) are very complex due to their inherent unsteadiness caused by large variations of the angle of attacks as the turbine is rotating and changing its azimuth angles simultaneously.

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 ...

Effects of blade section on performance of butterfly wind turbines as double-blade VAWTs
A butterfly wind turbine (BWT) is a kind of vertical axis wind turbine (VAWT) with closed-loop blades. These blades form a double-blade structure, which is expected to improve self-starting properties and reduce energy costs because of their simple ...

Power performance optimization of twin vertical axis wind turbine for farm applications
Twin Vertical Axis Wind Turbines (VAWTs) appear to be the potential candidates for enhancing the power density of wind farms. Earlier twin-VAWT studies were mainly focused on carrying out the parametric study of one or two twin-VAWT variables together ...

Studies on Vertical Axis Wind Turbine - A Review
A VAWT is the one turbine which rotor and shaft are kept in transverse direction to the direction of the wind. Due to this the motor or generator is kept on the ground. There are Darrieus, Savonius and Giromill types of VAWT are there.
