Experimental Study on Local Scour at the Monopile Foundation of an Offshore Wind Turbine under the Combined Action of Wave–Current–Vibration

Journal of Marine Science and Engineering
Monopile foundations are the most widely used offshore wind turbine foundations. The experiments were conducted to investigate the influencing factors of local scour around the monopile under the action of wave–current–vibration.

Estimation of Scour Depth at Bridge Piers by Using FASTER Model and Experimental Formulas [PDF]

مهندسی منابع آب, 2017
Bridges are one of the most important river structures. One of the main causes of bridge failure is local scour at bridge piers. Yearly, Many bridges failed around the world because of disregarding hydraulic factors.

Experimental study of local scour around diamond bridge piers subject to transverse standing waves

Ain Shams Engineering Journal, 2022
Numerous bridges around the world have been destroyed due to local scour around their piers and abutments. Transverse standing waves (perpendicular to the flow direction) generated by obstacles, such as bridge piers, can affect the extent of local scour ...

Local Scour at Bridge Abutments

Journal of King Abdulaziz University-Engineering Sciences, 1998
This paper presents the results of an experilnental investigation of local scour at bridge abutment models of three common shapes placed in laboratory flume with uniform sand with d)l) =0.775 mm. The 1l1uximum scour depths and extent of scour were determined corresponding to clear water conditions.

A Green Consumer‐Based Approach to Advance Branding Strategies in Experiential Consumption Contexts. Insight From the Cruise Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT Growing environmental awareness has intensified demand for sustainability and transparency, especially in cruise tourism, a high‐impact and highly scrutinised service context. This study examines how green consumption values (GCV) shape passengers' perceptions of the credibility of green marketing claims (believability) and, in turn, influence

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Study of the time-dependent clear water scour around circular bridge piers

Journal of Hydrology and Hydromechanics, 2017
The local scour around bridge piers influences their stabilities and plays a key role in the bridge failures. The estimation of the maximum possible scour depth around bridge piers is an important step in the design of the bridge pier foundations.
