Literature review of modification of u-type savonius wind turbine rotor for low wind speeds

Introduction

Literature review of modification of u-type savonius wind turbine rotor for low wind speeds. Explore modifications to U-type Savonius wind turbine rotors to enhance performance at low wind speeds. Learn how guide vanes and increased blades improve electrical energy generation.

Abstract

A wind turbine is one of the tools that can be used to convert wind energy into electrical energy. The increasing need for electrical energy in Indonesia and fossil fuels are running low, so alternative to fossil fuels are needed. One of them is a wind turbine that can convert wind energy into wind mechanical energy into kinetic energy in the form of turbine blades that are used to rotate generators that can produce electricity. Indonesia is an area that has low wind speed. This study aims to analyze the effect of U-type savonius wind turbine rotor modification at low wind speeds. The research method used is a qualitative method in which we conduct library research on various literature to examine the effect of turbine rotor modification. The results obtained are the addition of a guide vane or deflector and the increase in the number of blades on the turbine rotor can improve the performance of the U-type savonius wind turbine.

Review

This literature review addresses a highly relevant and timely topic: the modification of U-type Savonius wind turbine rotors for optimal performance in low wind speed environments, particularly within the Indonesian context. Given the global imperative to transition to renewable energy sources and the specific challenges posed by geographical wind patterns, investigating adaptations for vertical axis wind turbines is crucial. The paper's stated aim to analyze the effect of such modifications through a qualitative, library-based research method sets a clear scope for its contribution to the field. The primary strength of this work lies in its identification of practical strategies to enhance Savonius turbine efficiency, which is particularly valuable for regions characterized by low wind speeds. The abstract clearly highlights two key findings: the implementation of guide vanes or deflectors, and an increase in the number of blades, both indicated as promising methods to improve the performance of U-type Savonius wind turbines. These insights provide concrete starting points for further research and development, offering potential pathways for engineers and researchers to develop more effective and context-appropriate wind energy solutions. However, to elevate its impact, the full review could significantly benefit from a more rigorous and detailed methodological description. The abstract, while stating a "qualitative method" and "library research," offers limited insight into the specific search strategy employed, such as databases used, keywords, inclusion/exclusion criteria, or the number and nature of the literature reviewed. Furthermore, while the findings indicate that modifications "can improve performance," the abstract lacks specificity regarding the *extent* of improvement, the particular performance metrics enhanced (e.g., power coefficient, start-up torque, rotational speed), or any potential trade-offs. Providing quantitative or more detailed qualitative synthesis from the literature on these aspects would significantly strengthen the review's conclusions and their practical applicability.
