CFD investigation on wind power harvesting from small-scale wind turbines for powering residential buildings in New Zealand. [PDF]
J R Soc N ZABSTRACT As an alternative solution, wind power could be harnessed by designing and implementing small‐scale wind turbines for distributed power generation. In this work, 3‐dimensional time‐domain numerical simulations, based on the Reynolds‐Average Navier‐Strokes (RANS) model, are conducted for two categories of small‐scale wind turbines, i.e.

Performance Improvement of a Drag Hydrokinetic Turbine [PDF]
Water, 2021 Hydropower is at present in many locations, among all the other possible renewable energy sources, the best one for net cost per unit power. In contrast to traditional installation, based on water storage in artificial basins, free flow river turbines also provide a very low environmental impact due to their negligible effect on solid transport.

THE SUSTAINABLE POTENTIAL OF HYDROKINETIC TURBINES IN THE AMAZON BASIN
Anais do Congresso Nacional de Excelência em Gestão, 2023 The Amazon, rich in biodiversity and natural resources, seeks renewable energy sources to minimize environmental impacts and reduce dependence on non-renewable sources. Hydrokinetic turbines emerge as a promising alternative by making it possible to convert the kinetic energy of river currents into electricity, without the need for dams.
