Vertical axis wind turbines (VAWTs) are advantageous than horizontal axis wind turbines
(HAWTs) in terms of portability and ease of application in urban areas and turbulent …

The world's focus is shifting towards solar and wind energies which are primarily
contributing to renewable energy. Wind turbines are subdivided into horizontal axis wind …

The present study mainly focused on a new design of deflector by utilizing a rotating cylinder
to augment the overall performance of the drag-type Savonius turbine since the negative …

Savonius rotor is an attractive type of Vertical-Axis Wind Turbine (VAWT) for small-scale and
urban applications, due to its simplicity in design and self-starting capability. However …

The Savonius drag-type wind turbine suffers from poor efficiency due to the adverse
negative torques on the returning blades when they rotate against incoming flows. It was …

The depletion and the adverse effect on the environment caused by fossil fuels are critical
reasons to divert the power generation medium into non-fossil fuels (hydro, wind, solar, and …

The quest of clean and sustainable energy has grown rapidly all over the world in the recent
years. Among the renewable energy resources available, wind energy is considered one of …

This paper presents a Taguchi optimization study aimed at enhancing the efficiency of a two
bladed Savonius wind turbine by optimizing inner blade parameters. An L 9 orthogonal …

In this paper, we attempted to measure the effect of Bach's section, which presents a high-
power coefficient in the standard Savonius model, on the performance of the helical …

Liquid fossil fuel is anticipated to run out by the mid-2060s. The destruction of land, water,
and air due to fossil fuel use contributes to environmental degradation. Policymakers …
