WAKE CHARACTERIZATION IN ROW ARRAY OF HYDROKINETICS TURBINES

Revista de Engenharia Térmica, 2017
This study aims to obtain wake information, which passes through a linear array of turbines. Is presented a numerical approach to observe what effect can be obtained from a 2.2 meters turbines set. The linear array parameters were based on the Hydro-k project, in which two unconfined in-line rotors were used.

Technoeconomic Assessment of a Hydrogen‐Integrated Hybrid Microgrid for Island Electrification in Developing Countries

International Journal of Photoenergy, Volume 2026, Issue 1, 2026.
This study investigates the technoeconomic and environmental feasibility of a hybrid renewable energy microgrid designed for Dublar Char, a remote off‐grid island in Bangladesh. The proposed system integrates solar photovoltaic, wind turbines (WTs), a fuel cell, an electrolyzer, hydrogen storage, and a battery energy storage system (BESS) to deliver ...

Tests on a non-clogging hydrokinetic turbine

Energy for Sustainable Development, 2015
Abstract Hydrokinetic turbines (HKTs) are a promising technology for electrical power supply in small remote villages located in fairly flat, high rainfall country where other renewable energy technologies such as wind, solar and conventional micro-hydro are not suitable. However, clogging by floating debris has been identified as a major problem for

Performance and Flow Analysis of a Compact Airfoil Duct Turbine for Low‐Flow Hydrokinetic Energy in Small Open Channels: A Duct‐Augmented BEM Model, a Transient VOF‐CFD, and a Towing Tank Experimental Study

Journal of Engineering, Volume 2026, Issue 1, 2026.
Hydrokinetic turbines utilized in small rivers, irrigation canals, and constructed waterways function in flow conditions that are fundamentally distinct from those seen in broad channels or tidal locations. Such restricted locations impose stringent spatial, hydraulic, and ecological limitations, necessitating turbine designs that can efficiently ...

Hydropower Effluent as a Marine Pollutant; Impacts of River Regulation on Estuarine and Coastal Ecology

River Research and Applications, Volume 41, Issue 9, Page 1789-1802, November 2025.
ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.

Predicting Equilibrium Bed Morphology of Large‐Scale Meandering Rivers Using a Novel LES‐Trained Machine Learning Approach

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract Flood‐induced deformation of the bed topography of fluvial meandering rivers could lead to riverbank displacement, infrastructure failure, and the propagation of scour and deposition features. The ability to predict sediment transport in large‐scale meanders is, therefore, a critical requirement for tackling a host of environmental issues ...
