Startup Dynamics of Drag-Based Multibladed Vertical Axis Wind Turbine
Engineering ProceedingsA multibladed drag-based Vertical Axis Wind Turbine (VAWT) was developed and its startup dynamics evaluated using wind tunnel tests. The experimental data obtained for the time-based angular position of the rotor shaft at Aberdeen’s average wind speed of

Wind Energy, Volume 28, Issue 2, February 2025.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
Strain, Volume 61, Issue 1, February 2025.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 ...
