FEA Assisted Design and Structural Research on Vertical Axis Wind Turbine Rotor

The scope of the project is to perform finite element analysis of the Vertical axis wind turbine rotor assembly.Blade, arm, connectors and strings assembly of rotor are considered for analysis and to study the static behaviour at the different loading conditions. Total vertical load of 132 kg self-weight is acting downward direction to the structure. Considered that rotor will be rotating at maximum speed (RPM) aerodynamic load with self weight conditions. Due to higher angular velocity (154 RPM) blades will be subjected to great centrifugal force. Along with the centrifugal load rotor also will get subjected to fluctuating aero dynamic loads. In analysis it is considered as the rotor in stationary position and subjected to the maximum drag force at 52 (m/s) wind velocity at azimuth value of 90˚. SOLID92 is used for the 3-D modelling of solid structures. The maximum stress value obtained from the analysis is 183.1 N/mm2 for the loading and boundary conditions.

Wind Turbine Rotor

Much human energy needs are obtained from fossil fuels. This fossil energy is decreasing day by day. So that the utilization of natural energy such as solar energy, water energy and wind energy is being developed. Wind energy is energy that we can find, so it is very easy to use by using a turbine as the driving force. The vertical axis wind turbine is a type of wind turbine that is easier to apply in places where wind potential is not too large. This research was conducted by means of simulation using Qblade v0.963 software by comparing the influence generated from several numbers of wind turbine rotor blades. From the simulation process, it is known that the wind turbine rotor blades with 4 blades are the wind turbines capable of producing the greatest power, which is 75 Watts at a low TSR. So that in the manufacturing process it does not require large costs, but it still has to be built rigid and solidly.

Wind Turbine Rotor

Based on the small H-shaped vertical axis wind wheel model (NACA0016), a CFD wind wheel model was constructed. Based on the principle of moving grid, the grid division of the CFD wind wheel model is completed by using GAMBIT software, and the boundary conditions such as the inlet boundary and the outlet boundary are set reasonably. Then, the turbulence model and the couple algorithm are used to carry out transient simulation calculations, and finally the aerodynamic parameter curves of the two-dimensional CFD wind wheel model are obtained. Based on this, the matching characteristics of the wind turbine and generator of the small H-shaped vertical axis wind turbine are studied. The research results show as follows: when the incoming wind speeds change in range of (2 m/s, 12 m/s), and the power characteristic curve and torque characteristic curve of the generator wind wheel are respectively overlap the best power curve and best torque of the generator, the matching characteristics of the small H-shaped vertical axis wind turbine rotor and generator are optimal, which provides reference for carrying out related research.
