Hydrodynamic Analysis of Tidal Current Turbine under Water-Sediment Conditions

Journal of Marine Science and Engineering, 2022
The rivers connecting oceans generally carry sediment due to water and soil losses in China. Additionally, the maximum sediment concentration is 300 g/L, which is much higher than that of other countries.

Numerical simulations of biofouling effects on the tidal turbine hydrodynamic

International Marine Energy Journal, 2018
Biofouling by benthic organisms must be considered for tidal turbine operation and maintenance because it modifies hydrodynamics (drag and resistance) and could be detrimental to the turbine performance.

Lifetime Analysis of IGBT Power Modules in Passively Cooled Tidal Turbine Converters

Energies, 2020
Thermal cycling is one of the major reasons for failure in power electronic converters. For submerged tidal turbine converters investigating this failure mode is critical in improving the reliability, and minimizing the cost of energy from tidal turbines.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
