Wind Power Experiments Using an Electric Leaf Blower
  Location: KFC Courts
  Date: Monday, Aug.1
  Time: 8:45 PM -9:30 PM

  Abstract: Some simple experiments demonstrating basic principles of wind turbine operation can be carried out using an electric leaf blower in vacuum configuration as a wind source. A small DC hobby motor fitted with a model airplane propeller or a small fan blade serves as the generator, which is placed in front of the air intake of the leaf blower. The equipment required for quantitative experiments include a resistance box and voltmeter, some means of controlling the air speed, and an instrument to measure the air speed. Most departments will have resistors and voltmeters and probably a Variac for controlling the blower speed. The only special piece of equipment we purchased was a hot-wire anemometer to measure wind speed. Experiments suitable for a wide range of students will be described.
