CFD investigation on wind power harvesting from small-scale wind turbines for powering residential buildings in New Zealand. [PDF]

J R Soc N Z
ABSTRACT 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.
