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 ...

Numerical Study of Wake Characteristics in a Horizontal-Axis Hydrokinetic Turbine

Anais da Academia Brasileira de Ciências
Over the years most studies on wake characteristics have been devoted to wind turbines, while few works are related to hydrokinetic turbines. Among studies applied to rivers, depth and width are important parameters for a suitable design. In this work, a

Design and Prototype of a Micro Hydrokinetic Vertical Turbine

RE&PQJ
In Latin America only few countries are 100% connected to national electric networks. In Colombia, 52% of the national territory is known as Non Interconnected Zones with a population of 2 million people. To cover these zones basic electricity needs, the use of natural, local and renewable resources such as the hydraulic is proposed, due to the high ...

Guidelines for simulating hydrokinetic turbine arrays

, 2023
The extraction of energy from flowing water in rivers and tidal regions is gaining acceptance around the world as a means of generating electricity without the use of conventional hydropower dams. The purpose of this guideline is to provide a uniform methodology that will ensure consistency and accuracy in the estimation, measurement, characterisation,
