Blade force measurement and flow visualization of Savonius rotors.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1985 For the purpose of clarifying the mechanism of rotation of Savonius rotors, ones which have two semicylindrical blades are studied experimentally. The force acting on a blade is measured in a water two tank for both cases where a rotor is at rest and rotated.

Wind Energy, Volume 28, Issue 8, August 2025.ABSTRACT Wind energy is the most mature renewable energy technology; however, its exploitation in cities is often met with skepticism. Thanks to their ability to operate at low wind speed regardless of direction, vertical axis wind turbines (VAWTs) offer an attractive opportunity for wind energy harvesting in cities. However, limited evidence exists on

Aeroacoustic Effect of Savonius Rotor Segmentation
Archives of AcousticsSwitching to renewable energy has been accelerated in recent decades due to the depleting fossil fuel reserves and the need to mitigate environmental and climate degradation. Wind power, especially in urban areas, has seen a significant growth. A critical consideration in the urban wind turbine installation is the noise impact on residents.

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.

A High‐Durability Triboelectric Nanogenerator for Broad‐Spectrum Wind Energy Harvesting
Advanced Materials Interfaces, Volume 12, Issue 14, July 25, 2025.This study presents an easy‐starting and high‐durability triboelectric nanogenerator (ESHD‐TENG) for efficient broad‐spectrum wind energy harvesting. By integrating a fan blade design and a mode‐switching mechanism, the device achieves a low cut‐in wind speed of 0.9 m −1s and significantly enhanced durability, addressing key challenges in current TENG ...
