Design and Prototype of a Micro Hydrokinetic Vertical Turbine
RE&PQJIn 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 ...

Determination of wind turbine far wake using actuator disk [PDF]
, 2014 The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of upcoming wind cannot be valid. The

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,

Directional Variations in Tidal Flow Multifractality and Intermittency
Journal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.Abstract We explored distinct directional variations of multifractal and intermittent characteristics of ebb and flood flow velocities at nodule point, WA, tidal energy site, and complementary inspection on the East River, NY using scaling exponents of the structure function, distribution flatness, detrending moving average (DMA) analysis, multifractal

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.Hydrokinetic turbines are essential for sustainable power generation, but impacts can hinder their efficiency from sediment and debris. This study numerically evaluates the performance of Darrieus‐type vertical axis turbines with straight and Coanda‐type grates under varying design angles. The research uses ANSYS Fluent to highlight the turbines' power

Marine Fish Passage—Underappreciated Threats to Connectivity Within the Marine Environment
Marine Ecology, Volume 46, Issue 1, January 2025.ABSTRACT Habitat fragmentation is a major threat to aquatic biodiversity loss. However, much of the focus is on the connectivity of freshwaters, with much less attention given to marine ecosystems. We contend that coastal infrastructure including bridges, causeways, tidal turbines, land infilling and harbours, wharfs, quays, piers and docks have ...
