Abstract From the past decades it’s quite interesting that the investigation of Vertical Axis Wind Turbine and its characteristics of modeling made traumatic changes in manufacturing process of wind turbines. The key interest in wind energy harvesting in offshore as well as in the urban regions, Vertical Axis Wind Turbines (VAWTs) have recently received keen interest. Due to their combining form in all direction characterized the experience to build particular model while their low installation cost makes them highly suitable for offshore wind farms. As comparing with Horizontal Axis Wind Turbines (HAWTs) they required further performance optimization to comparatively gain higher power coefficient (Cp). This can be attributed both to the complexity of the flow around VAWTs and the significantly smaller amount of research they have received. The potential parameters like design, mechanism and system arrangement is to enhance the performance of VAWTs. The current study investigates the variations in loads and moments on the turbine as well as the experienced angle of attack; shed vorticity and boundary layer events (leading edge and trailing edge separation, laminar-to- turbulent transition) as a function of potential parameters using Fundamental / Finite Element Analysis (FEA) calculations. XDirect analysis start from -10 degree to 20 degree in delta 0.5 degree increment are investigated using steady Reynolds-Averaged Navier-Stokes (URANS- 1000000) of fixed speed cl/cd calculations, referencing HAWT, while simulation is modelled with the transition LLT model. The results show that with laps number of timestpes in Cp can be achieved using potential parameters. Additionally, it is found that a change in chords and radius; shifts instantaneous loads and moments between upwind and downwind halves of the turbine. The shift in instantaneous moment during the revolution for various potential parameters suggests that dynamic rotation might be a very promising approach for further performance optimization.

I. INTRODUCTION In the history of mankind, wind energy has played a crucial role. Among the other sources of energy, wind energy was hard to seed it out during past days. These so called wind mills are of the horizontal axis design and were also used for pumping water, grinding grains and later for sawing woods etc. Using aerodynamic shaped blades the wind energy from the atmosphere is converted to kinetic energy by the turbine which further used for the several purpose. Since, it is quite fair to state that Renewable Energy technologies are one of the most demanding disciplines on account now a days the broad range of competences, the manufactures and implementers call to from the design engineers team to design process, an excellent example is provided by the NIWE, India, in present stage where mechanical engineer and electrical engineer work together to solved the problems in the design of a wind turbines and its parameters. With populations increasing exponentially and our natural resources being strained by increases in demand, it is more important than ever to invest in Renewable Energy, our consumption of fossil fuels as energy has been traced to be a leading cause in environmental issues and at the stage of varnishing from the earth. The by- products of fossil fuels such are carbon dioxide, carbon monoxide and so many toxic gases which have been named to be a primary constituent leading to Global Warming and depletion of many living species. As more attention was put on the environmental issues the fundamental bodies are putting much pressure in developing eco-friendly energy recourses thus the development of eco-friendly energy such as wind energy, solar energy and tidal energy etc. are becoming more challenging day by day. The goal of this project is to create a vertical axis wind turbine capable of producing electricity in a residential setting. The project will focus on creating a vertical-axis wind turbine that is simple to manufacture while at the same time highly efficient and cost effective.
