1. Introduction

At the end of the 20th century, the inert wind turbine technology awoke to a world of new opportunities. The resurgence has been accelerated by technological advancements in several other fields that were applied to wind turbines. The current generation of wind turbines has been influenced by several fields, including material science, computer science, aerodynamics, testing, analytical techniques, and power electronics. New alloys and composites for metal parts and blades have been made possible by material science. Computer science advancements make design, monitoring, analysis, and control easier. Originally created for the aerospace field, aerodynamics design techniques are now used to wind turbines. The state of analytical approaches has advanced to the point where it is now feasible to grasp how a new design should function far more clearly than it was in the past. Through testing with the wide range of commercially accessible sensors and data gathering and analysis tools, designers are able to gain a deeper understanding of the real performance of the new turbines.

Wind turbines are a very new and somewhat growing fast method of producing electricity. Power electronic devices can transmit energy to and from storage, permit small-scale isolated network operation, and allows the turbine to run at a variable speed, increasing energy production, decreasing fatigue of damage, and benefits the usefulness in the process. They can also assist in easily integrating the turbine's generator into the electrical system. The patterns of wind turbines have altered dramatically in the last 25 years. They are quieter, more affordable, and more dependable. However, the end of the evolutionary epoch cannot be declared. At locations with lesser wind speeds, it ought to still be feasible to cut the cost of electricity. It still has to be economically feasible to create turbines for usage in isolated settlements. Offshore wind energy is still in its early phases of development. Offshore areas provide amazing prospects, but there are also a lot of challenges to face. Intermittency transmission and storage concerns need to be taken up again as wind energy becomes a bigger source of electricity globally. The need on designers to increase wind turbines' cost-effectiveness across the board will not go away. It will be necessary to use better engineering techniques for mass-produced production, design, and analysis. There are also chances for the creation of novel materials to lengthen the lifespan of wind turbines. It will be necessary to pay more attention to the specifications of special applications. In any situation, the development of the wind business poses both a problem and an opportunity for a variety of fields, including computer science, mechanical, electrical, materials, aerospace, controls, and civil engineering.

This thesis's main goal is to thoroughly design and assess the performance of a new type of wind turbine blade. The goal is to make a useful contribution to the arena of wind energy by a combination of theoretical research, computational modelling, and hands-on experimentation. The particular goals consist of: Create a thorough and well-thought-out design for a wind turbine blade, taking structural integrity, materials, and aerodynamics into account. This entails putting existing blade design ideas to use while incorporating cutting-edge technologies to improve performance.

Aerodynamic Analysis: To simulate and examine the intended wind blade's aerodynamic behavior, use CFD computational tools. This involves determining the best possible energy collection under varied wind conditions by evaluating lift and drag forces, flow patterns, and turbulence effects. Performance Optimization: Apply the insights from the structural and aerodynamic evaluations to iteratively improve the design. A balanced and effective performance that maximizes energy extraction while upholding durability and safety is the aim. Comparative Analysis: Evaluate the new blade's performance against that of the current standard designs. This comparison analysis sheds light on the possible gains in cost-effectiveness, environmental impact, and energy efficiency that the suggested design may bring.

Wind power has become a viable option as people's awareness of the need for sustainable energy grows. The large, revolving structures known as wind turbines are essential to using wind power to create energy. We may frequently see them on the horizon. The idea behind this thesis is that a cleaner, more sustainable energy future can be greatly aided by comprehending and improving the architecture of these turbines. This research is driven by the straightforward idea that the world needs greener energy sources, and wind power is one of them. As the effects of utilizing fossil fuels weigh heavily on us, it is becoming more and more important to switch to greener options. A future when our energy comes from a source as natural as the wind is promised by wind turbines, which are a concrete step in that direction.

However, this drive extends beyond merely advancing technology. It's about making a contribution to the wider discussion on renewable energy. Despite their magnificent appearance, wind turbines are not without problems. These include wear and tear and changes in the wind. In order to address these issues head-on, this thesis offers suggestions that can strengthen and improve the resilience of wind turbines. The way the world produces energy needs to change, and it needs to happen quickly. This transition is even more critical in light of climate change and environmental issues. With its unrealized potential and sustainability, wind energy is urging us to move towards a greener future. By examining the design and optimization of wind turbines, this thesis hopes to contribute to this significant shift, which will not only enhance wind energy but also move us closer to a future in which we coexist peacefully with the natural world. The wind turbine's blades represent our dedication to a more sustainable and environmentally friendly future as we move closer to a new era of renewable energy.
