Variability of Internally Generated Turbulence in an Estuary, from 100 Days of Continuous Observations [PDF]

open access: yes, 2009
We present detailed observations of internally generated turbulence in a sheared, stratified natural flow, as well as an analysis of the external factors leading to its generation and temporal variability.

Scenario Analysis of Cost-Effectiveness of Maintenance Strategies for Fixed Tidal Stream Turbines in the Atlantic Ocean

open access: yesJournal of Marine Science and Engineering, 2023
This paper has developed an operation and maintenance (O&M) model for projected 20 MW tidal stream farm case studies at two sites in the northeast Atlantic in France and at EMEC’s Fall of Warness site in the UK.

Determining the galactic mass distribution using tidal streams from globular clusters [PDF]

open access: yes, 1999
We discuss how to use tidal streams from globular clusters to measure the mass distribution of the Milky Way. Recent proper motion determinations for globular clusters from plate measurements and Hipparcos astrometry provide several good candidates for ...

Tidal stream energy resource assessment of the Anglesey Skerries [PDF]

open access: yesInternational Journal of Marine Energy, 2013
Abstract Many candidate sites for tidal stream power devices can be classified as headlands. This paper analyses one such site, off Anglesey. In order to investigate the disturbance to the local flow field due to the operation of tidal arrays and evaluate the extractable power at the site, a two-dimensional depth-averaged shallow water model of the ...

Modeling Assessment of Tidal Energy Extraction in the Western Passage

open access: yesJournal of Marine Science and Engineering, 2020
Numerical models have been widely used for the resource characterization and assessment of tidal instream energy. The accurate assessment of tidal stream energy resources at a feasibility or project-design scale requires detailed hydrodynamic model ...

The downstream wake response of marine current energy converters operating in shallow tidal flows

open access: yes, 2011
This paper presents findings from an experimental study investigating the downstream wake response from marine current energy convertors operating in various degrees of vertical flow constraint. The paper investigates deep vertically unconstrained sites,

Self-intersection of the Fallback Stream in Tidal Disruption Events [PDF]

open access: yes, 2019
We propose a semi-analytical model for the self-intersection of the fallback stream in tidal disruption events (TDEs). When the initial periapsis is less than about 15 gravitational radii, a large fraction of the shocked gas is unbound in the form of a ...

Assessment of the Malaysian Tidal Stream Energy Resources

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract As a developing country, Malaysia has shown great interest and effort to commit and invest for green technology and green energy especially tidal energy resources. This research project is conducted to carry out an assessment study to analyse and compare several locations in Malaysia while using the optimal analytical approach ...
