Abstract - Bladeless wind turbines use vortex shedding to
long-term energy supply. It is also cost effective as wind is freely available in abundant quantities.
harvest wind energy. A bladeless wind turbine converts wind energy into mechanical energy, which is then turned into electrical energy using piezoelectric sensors. In the creation of bladeless wind turbines, we first assessed the necessity to transition to renewable energy sources. This helped us outline the project's goals and objectives. Based on this research, an analysis was undertaken to collect important data, which was then used to create the CAD model. The bladeless wind turbine was then produced and tested, with different design made to boost output and efficiency. The output of the bladeless wind turbine increased with increase in quantity and size, increase in the outer diameter of the dome, and change in the material of the circular disc.
Wind turbines come in a variety of designs, such as verticaland horizontal-axis models. The sort of turbines that rotate along a horizontal axis are called horizontal-axis turbines, and they are the most often used. In contrast, a rotor having blades that rotate along a vertical axis is observed in vertical-axis turbines. However, there are several drawbacks to wind energy as well, such as the requirement for steady wind speeds and the possible influence on animals and the natural environment. Bladeless wind turbines are a relatively new technology that aims to provide an alternative to traditional wind turbines. As they have cone shape mast instead of blade they do not have any rotating blades that could harm wildlife and reduced noise pollution.
Key Words: Renewable energy, Wind energy, Vortex Shedding, Wind turbine.
1.INTRODUCTION
1.1 BLADELESS WIND TURBINE
Renewable energy refers to sources of energy that are replenished naturally and can be continuously utilized without depleting finite resources. Renewable energy is also referred to as clean energy as it doesn't produce harmful pollutants or emissions that are harmful to the environment. Solar energy is the most abundant renewable energy source, obtained from the sun's radiation, and it can be harnessed through the use of photovoltaic panels. Another renewable energy source that uses wind turbine power is wind energy.
Bladeless wind turbine is to generate clean and sustainable energy while minimizing the negative impacts on the environment and wildlife. Unlike traditional wind turbines with rotating blades, bladeless wind turbines utilize a different mechanism, such as the vortex shedding effect, to capture wind energy. This design eliminates many of the issues associated with traditional wind turbines, such as noise pollution, bird strikes, and the need for expensive maintenance.
1.2 PROBLEM STATEMENT
Energy from wind has been utilised for thousands of years because it is abundant, clean, and dependable. Reducing greenhouse gas emissions, air pollution, and reliance on foreign oil is achieved by the usage of this sustainable substitute for fossil fuels. Recently, as nations all over the world have been trying to take themselves away from fossil fuels and move towards greener energy sources, wind energy has become more popular. India is currently at the forefront of developing countries in terms of economic growth and development. Therefore, as India continues to grow and develop economically, its energy demand is expected to increase significantly in the upcoming decades. However, its relatively low energy concentration per unit area can make it expensive to produce compared to other energy sources. Therefore wind energy is the best choice because it has numerous advantages, including its clean and sustainable nature and its ability to provide a stable and
