The effect of hybrid savonius and darrieus turbine on the change of wake recovery and improvement of wind energy harvesting

The energy crisis encourages the development of renewable energy; one of the potential renewable energy is wind. In the field of wind turbine there is a two-way development of the utilization of wind energy, first by making a large wind turbine, the second by making a wind farm energy with a relativ...
