Project Objectives

The objective of the teams study is to find a suitable location for the Whisper 200 Wind Turbine on the Stevens Institute of Technology campus where it will provide optimal power generation levels. An insufficient amount of wind speed and constant directional wind is currently present on the Babbio Center Roof which in return causes the turbine blades to not spin correctly. As a result, the current location of the Whisper 200 needs be analyzed and/or modified in order to obtain better performance. By acquiring wind velocity and directional data at the present location as well as various different locations across campus, we will determine where the Whisper 200 can be relocated in order to satisfy the manufacturer’s power generation requirements. After a suitable location is determined, additional testing and analysis will be performed to prove that the Whisper 200 is producing power while limiting any other problems that may occur.

Current Applications

The two main types of wind turbines designs in use today are defined by whether they rotate about either a horizontal or vertical axis. Horziontal axis turbines are propeller type toros mounted on a horizontal axis. The rotor needs to be positioned into the wind direction through the means of a wind tail. Horizontal axis turbines are sensitive to changes i wind direction and turbulence which has a negative effect on performance due to repositioning of the turbine. Horizontal axis turbines also have a large swept area allowing them capture more wind.

Vertical axis turbines have the main rotor shaft arranged vertically with blades running along the height of the turbine. The advantage with a vertically arranged turbine is that it does not need to be pointed into the direction of the wind to be effective. The overall efficiency is lower than horizontal axis turbines but the start up speed is lower. Also it is difficult to mount a vertical axis turbine on a tower so they are installed typically on ground leve which can take advantage of locations where wind is channelled.

Urban Turbines

Most wind turbines have been installed in large open areas where the wind flow is uninterrupted and steady, allowing for high energy yield. Recently there has been a large push towards urban wind turbines that are installed on building tops to offset reliance on the electrical grid. New technologies are being developed that help increase the efficiency and cost-effectiveness on installing such turbines.
