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.

Simulating Collisions for Hydrokinetic Turbines [PDF]
, 2013 Evaluations of blade-strike on an axial-flow Marine Hydrokinetic turbine were conducted using a conventional methodology as well as an alternative modeling approach proposed in the present document. The proposed methodology integrates the following components into a Computa- tional Fluid Dynamics (CFD) model: (i) advanced eddy-resolving flow ...

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.
