Brandetti, L. (author), Mulders, S.P. (author), Merino Martinez, R. (author), Watson, S.J. (author), van Wingerden, J.W. (author)Vertical-axis wind turbines (VAWTs) are considered promising solutions for urban wind energy generation due to their design, low maintenance costs, and reduced noise and visual impact compared to horizontal-axis wind turbines (HAWTs). However, deploying these turbines close to densely populated urban areas often triggers considerable local...review 2024

Khoshmanesh, S. (author), Watson, S.J. (author), Zarouchas, D. (author)Wind turbine blades carry the risk of impact damage during transportation, installation, and operation. Such impacts can cause levels of damage that can propagate throughout the structure compromising performance and safety. In this study, the effect of impact damage on fatigue damage propagation in test specimens representative of a spar cap...journal article 2024

Iori, J. (author), Zaaijer, M B (author), von Terzi, D.A. (author), Watson, S.J. (author)For scenarios of high penetration of renewable energy, it becomes increasingly relevant to improve the dispatchability of supply for wind and solar power plants. Baseload power plants, required to produce a minimum power production at all times, are discussed in this context. The baseload constraint can be satisfied with renewable sources when...conference paper 2024

Gutierrez, Ivan (author), Lindenbergh, R.C. (author), Watson, Lisa (author), Shelton, Kim (author)Detailed 3D information on vulnerable archaeological sites can document cultural heritage and contribute to its preservation. The Late Bronze Age Mycenaean cemetery of Aidonia, Greece, is a representative case of a vulnerable site. Tomb looting has occurred sporadically since the 1970s, when the Greek government was made aware of the site....journal article 2024

Zhang, Y. (author), Avallone, F. (author), Watson, S.J. (author)In this paper, the feasibility of using far-field acoustic measurements as a non-contact monitoring technique for wind turbine blade leading edge erosion is assessed. For this purpose, a DU96 W180 airfoil with several eroded leading edge configurations of different severities is experimentally investigated. The eroded leading edges are designed...journal article 2023

Hasan, Razi (author), Watson, Barry (author), Haworth, Narelle (author), Oviedo-Trespalacios, O. (author)Despite a strong reliance on enforcement approaches to prevent drug driving in Australia, this behaviour is still prevalent. The objective of this study was to investigate the influence of problematic drug use (i.e., showing indications of addiction), exposure to roadside drug testing, the use of detection avoidance strategies, and perceptions...journal article 2023

Khoshmanesh, S. (author), Watson, S.J. (author), Zarouchas, D. (author)In this paper, a new indicator to localize fatigue damage in a fibre glass composite structure, i.e. spar cap to shear web thick adhesive joint of a wind turbine blade, is presented. This indicator is based on the effect of damping on the phase of the mode shapes of the structure. When fatigue damage occurs, damping increases in the defective...journal article 2023

Cheneka, B.R. (author), Watson, S.J. (author), Basu, S. (author)Only a few studies on the overall impact of climate change on offshore wind power production and wind power ramps in the North Sea region have been published. This study focuses on the characteristics of expected wind power production and wind power ramps in the future climate aided by the classification of circulations patterns using a self...journal article 2023

Hasan, Razi (author), Watson, Barry (author), Haworth, Narelle (author), Oviedo-Trespalacios, O. (author)Drug driving is recognised as a major road safety problem in many countries. In Australia, the primary response to this problem involved the adoption of roadside drug testing (RDT), which was modelled on the policies and practices used to conduct random breath testing (RBT) for alcohol. However, there remain important differences in the way that...journal article 2023

Unscented Kalman filter-based blade-effective wind speed estimation for a vertical-axis wind turbineBrandetti, L. (author), Liu, Y. (author), Pamososuryo, A.K. (author), Mulders, S.P. (author), Watson, S.J. (author), van Wingerden, J.W. (author)On-shore horizontal-axis wind turbines (HAWTs) provide a cost-effective solution for low carbon electricity generation. However, public acceptance is still a problem. A possible alternative to a HAWT is a vertical-axis wind turbine (VAWT), which is more visually appealing and less noisy. Furthermore, the inherent omni-directionality of VAWTs...journal article 2023

Kartal, S. (author), Basu, S. (author), Watson, S.J. (author)Peak wind gust (Wp) is a crucial meteorological variable for wind farm planning and operations. However, for many wind farm sites, there is a dearth of on-site measurements of Wp. In this paper, we propose a machine-learning approach (called INTRIGUE, decIsioN-TRee-based wInd GUst Estimation) that utilizes numerous inputs from a public-domain...journal article 2023
