  • Wind Turbine Write Up
    Jankowski 1 Wind Turbine Write up By: Matt Jankowski EDSGN 100 Sec 014 Windmill Background Wind turbines are an essential tool for capturing natural energy and are very simple to understand the mechanisms behind. It’s as simple as instead of using electricity to create wind, such as a fan or an AC unit, wind turbines use wind to create electricity. Humans have used wind to power mechanisms and toys for decades, such as setting sail on a sailboat to flying a kite on a windy day. Then we took those ideas and turned it into a way to create energy. The rotor blades on windmills act as the blades on a helicopter and are set at 20 degree angles, which will produce the most rotor rotation. When the wind blows, it catches on the blades and causes the rotor to spin. The rotor is either directly connected to or connected through a series of gears to a generator. The generator runs, produces electricity and stores it to be used. My Windmill My solidworks model consists of eight different parts, assembled together to make a free-standing horizontal windmill. First, I started by connecting the base and the lower mast with three mates: concentric, coincident and front plane-front plane coincident. I then added the upper mast and swivel shaft, using three mates to add them to the assembly. Next, three blades, the hub and the main shaft were added. To assemble the blades into the hub, I had to make three mates: concentric, coincident, and a 20 degree angle between the right plane and the flat surface of the blade.

Its performance was predicted using a computational fluid dynamics model. The proposed wind turbine has two blades with a radius of 0.29 m and a height of 1.30 m. Ansys Fluent, a commercial computational fluid dynamics solver, was used to predict the performance, and the k-omega SST model was used as the turbulence model. The simulation result revealed a tip-speed ratio of 0.54 with a maximum power coefficient, or an aerodynamic rotor efficiency of 0.17. A wind turbine was installed at a measurement site to validate the simulation, and a performance test was used to measure the power production. To compare the simulation results obtained from the CFD simulation with the measured electrical power performance, the efficiencies of the generator and the controller were measured using a motor-generator testbed. Also, the control strategy of the controller was found from the field test and applied to the simulation results.

  • Chapter 1 History
    CHAPTER 1 HISTORY 1.0 INTRODUCTION Since early recorded history, people have been harnessing the energy of the wind. Wind energy propelled boats along the Nile River as early as 5000 B.C. By 200 B.C., simple windmills in China were pumping water, while vertical-axis windmills with woven reed sails were grinding grain in Persia and the Middle East. New ways of using the energy of the wind eventually spread around the world. By the 11th century, people in the Middle East were using windmills extensively for food production; returning merchants and crusaders carried this idea back to Europe. The Dutch refined the windmill and adapted it for draining lakes and marshes in the Rhine River Delta. When settlers took this technology to the New World in the late 19th century, they began using windmills to pump water for farms and ranches, and later, to generate electricity for homes and industry. Industrialization, first in Europe and later in America, led to a gradual decline in the use of windmills. The steam engine replaced European water-pumping windmills. In the 1930s, the Rural Electrification Administration's programs brought inexpensive electric power to most rural areas in the United States. However, industrialization also sparked the development of larger windmills to generate electricity. Commonly called wind turbines, these machines appeared in Denmark as early as 1890. In the 1940s the largest wind turbine of the time began operating on a Vermont hilltop known as Grandpa's Knob. This turbine, rated at 1.25 megawatts in winds of about 30 mph, fed electric power to the local utility network for several months during World War II.
