Conceptual Design of Vertical Axis Wind Turbine and Moulding through Fiberglass

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.
