Journal of the Royal Society of New Zealand, Volume 55, Issue 4, Page 977-1004, August 2025.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.

Experimentally Determining the Optimum Design Configuration for Savonius Rotors
Bulletin of JSME, 1986 The Savonius rotor was proposed in the early 1920's. Until now, there has been no systematic work on the optimum design configuration of Savonius rotors. Therefore, in the present work, various model tests were carried out in a wind tunnel, in order to ascertain the optimum design configuration of Savonius rotors.
