Presentation Transcript

  1. CDCA Presentation • Tiernan Garsys

  2. Background • Sophomore at AMHS (Provided with Rapid Prototyping Machine by CDCA in 2008) • Required to complete Science Fair project; chose to do project in field of engineering. • Interested in alternative energy, especially wind power.

  3. Research • Required to perform research on topic prior to experimentation. • Interested in differences between Vertical Axis Wind Turbines (VAWTs) and Horizontal Axis Wind Turbines (HAWTs)

  4. HAWTs • Generally capable of producing more energy than VAWTs, due both to tower height and lack of “backtracking” • Direction and blade pitch can be changed for optimum efficiency. • Relatively difficult to transport, install, and maintain. • Require an additional yaw mechanism to consistently face wind.

  5. VAWTs • Relatively simple to transport, install, and maintain. • Generally more versatile in terms of placement, due both to smaller nature and ability to accept wind from any direction. • Generally unable to produce as much energy as HAWTs, due to “backtracking” effect and lower placement to ground.

  6. “Backtracking” Effect

  7. Proposed Change

  8. Results • Attachment of cover generated significant difference in performance of wind turbines. • Some orientations increased turbine performance, while others reduced turbine performance.

  9. Conclusions • Increases efficiency in a small spectrum of wind directions, while hindering efficiency in other orientations. • Possibly viable for use in areas where wind direction is fairly certain (where VAWTs would otherwise be used).

  10. Contribution of Rapid Prototyping Machine • Allowed for quick, precise construction of models for experimentation. • Facilitated design on the computer, drastically reducing “trial-and-error” of fabrication process.
