Abstract

The helical Savonius rotor (HSR) is used as green energy generation. The accurate design of HSR is essential before installing any wind farm in a region. It has been widely employed that positive static torque coefficients of helical Savonius rotor are higher compared to conventional semicircular rotor stated by several researchers. The reason is behind that the formation of secondary vortex of fluid. It is leading by vertical vortex flow, which passes over the curve surface and creates drag force. Still now, various design have been proposed to meet peak power output through optimum geometry parameters like blade profile design, aspect ratio and overlap ratio. The selection of blade material is also the influencing parameter to improve the starting torque of the rotor. In this regards present paper is aim to study the details experimental, numerical, and analytical review on HSR and selection of blade material with minimum production cost.

螺旋萨沃纽斯转子的设计、开发、分析和叶片材料选择综述

螺旋Savonius转子(HSR)被用作绿色能源发电。在一个地区安装任何风电场之前，高铁的精确设计至关重要。螺旋萨沃纽斯转子的正静转矩系数比传统的半圆转子高，这一观点已被广泛采用。其背后的原因是流体二次涡的形成。它是由垂直涡旋引导的，垂直涡旋流过曲线表面并产生阻力。到目前为止，已经提出了各种设计方案，通过优化叶型设计、展弦比和重叠比等几何参数来满足峰值功率输出。叶片材料的选择也是提高转子起动转矩的影响因素。在这方面，本文的目的是研究详细的实验，数值和分析综述的高铁和叶片材料的选择，以最小的生产成本。

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
