Design of a windmill for pumping water

In our design, we used a horizontal axis windmill with 24 blades. Each blade has a radius of 2 m giving a total surface area of 0.5585 m2 and this gives a solidity of 0.8, the minimum theoretical optimum value for windmills. The torque output of the windmill is 106.4572 Nm and this is sufficient to sustain the desired

Vertical axis small wind turbines are a more efficient choice than horizontal wind turbines, especially when it comes to residential applications. Vertical wind turbines are often cheaper, easier to maintain, and require less space. They also handle turbulent winds better than horizontal turbines.

Types of wind

Vertical-axis turbines look like egg beaters. Vertical-axis turbines have blades that are attached to the top and the bottom of a vertical rotor. The most common type of vertical-axis turbine—the Darrieus wind turbine, named after the French engineer Georges Darrieus who patented the design in 1931—looks like a giant, two-bladed egg beater ...

Clark University Clark Digital Commons

Horizontal axis wind turbines (HAWTs) are the dominant wind gathering technology because they have higher efficiency ratings [14]. Their main advantage is that their blades move perpendicular to the flow of wind so energy can be generated the entire way through a rotation [14]. Another type of turbine, the vertical axis wind
