Research on the Blade Motion of a Bidirectional Energy-Generating Turbine under Integrated Wave and Tidal Current Action

open access: yesJournal of Marine Science and Engineering, 2021
An integrated wave-tidal current power turbine is affected by both wave and tidal current forces, and its energy efficiency is closely related to the velocity and direction of the two forces.

Subtidal secondary circulation induced by eddy viscosity-velocity shear covariance in a predominantly well-mixed tidal inlet

open access: yesFrontiers in Marine Science, 2023
The secondary circulation in a predominantly well-mixed estuarine tidal inlet is examined with three-dimensional numerical simulations of the currents and density field in the German Bight.

Systematic assessments of tidal wetlands loss and degradation in Shanghai, China: From the perspectives of area, composition and quality

open access: yesGlobal Ecology and Conservation, 2021
Salt marshes and tidal flats are ecosystems providing considerable value to human beings and widely distributed in the world temperate coastal zone. However, they have been seriously damaged due to human activities over the past half century.

Computational Fluid Dynamics-based Simulation and Design of a Horizontal Tidal Turbine System [PDF]

open access: yesE3S Web of Conferences, 2023
Tidal phenomena, the rhythmic rise and fall of sea waters due to gravitational forces among celestial bodies like the Sun, Earth, and moon, offer a dependable source of renewable energy.

The tidal force function and tidal torques [PDF]

open access: yesStudia Geophysica et Geodaetica, 1996
The tidal force function of the two-body system is defined. It is formed by two parts, reflecting the direct, as well as, the indirect tidal effects. It enables deriving the tidal torques due to both the tidal effects independently of density distributions.

Tidal forces in naked singularity backgrounds [PDF]

open access: yesPhysical Review D, 2015
The end stage of a gravitational collapse process can generically result in a black hole or a naked singularity. Here we undertake a comparative analysis of the nature of tidal forces in these backgrounds. The effect of such forces is generically exemplified by the Roche limit, which predicts the distance within which a celestial object disintegrates ...

Tidally-forced turbulence in planetary interiors [PDF]

open access: yesGeophysical Journal International, 2016
The turbulence generated in the liquid metal cores and subsurface oceans of planetary bodies may be due to the role of mechanical forcing through precession/nutation, libration, tidal forcing and collisions. Here, we model the response of an enclosed constant density fluid to tidal forcing by combining laboratory equatorial velocity measurements with ...

Tidal effects in 4D Einstein–Gauss–Bonnet black hole spacetime

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We have investigated tidal forces and geodesic deviation motion in the 4D-Einstein–Gauss–Bonnet spacetime. Our results show that tidal force and geodesic deviation motion depend sharply on the sign of Gauss–Bonnet coupling constant.

FSI analysis of deformation along offshore pile structure for tidal current power

open access: yes, 2013
Due to global warming, the need to secure an alternative clean energy resource has become an international issue. Tidal current power is now recognized as one of the clean power resources in Korea, where there are many strong current regions on the west ...
