A review of Darriues Hrotor vertical axis wind turbine with porous blades

Over the world, advancements in the design of wind turbines with augmentation are being made with the aim of producing electricity nearby users in built-up regions. By reducing the distance between the consumer and the power source, this is certain to aid in lowering the burden on the power generation system as well as the costs associated with the distribution and transmission network. By maximizing the upstream wind striking on the rotor blades, the major goals driving the development and progress of vertical-axis wind turbines (VAWTs) are raising the power coefficient and torque coefficient. VAWT produce both positive and negative torque while operating, in contrast to horizontal axis wind turbines (HAWTs). For VAWTs, the negative torque produced by the returning blade is a major problem that is counterproductive. When used to boost flow, porous blades lessen the negative torque generated by the return blades and also increase the torque by causing upstream airflow to be bent toward the leading blade. The studies conducted so far on the Darriues VAWT with porous blades are examined in this paper. Research results show that Darriues VAWT with porous blades has recorded more self-starting and turn than the Darriues VAWT base with straight blades. Moreover, the ability to self-starting torque, power, force less than the vertical axis of Darriues is required with straight blades.
