Wind Mill

  1. 2. Wind mill <ul><li>Basic requsirments to run a wind mill </li></ul><ul><li>Atmospheric pressure: to run a wind mill properly for energy purpose the atm pressure is 8.5bar. </li></ul><ul><li>Height: after every 10 meters wind mills efficiency incresed with 100%. </li></ul><ul><li>It should not be a poor remake of an existing design </li></ul>
  2. 3. Wind mill design <ul><li>Design of blades: it should be make airfoil, elongated and static. </li></ul><ul><li>Blade type: naca 44, naca 63. </li></ul><ul><li>The design shuold be able to face all weather conditions. </li></ul><ul><li>Gear box, shafts & etc all component are well maintained or connected. </li></ul><ul><li>Airfoil Design – “Design from the Side” </li></ul><ul><li>Planform – “Design from the Top” </li></ul><ul><li>Aspect Ratio – “Squat or Elongated” </li></ul><ul><li>Twist </li></ul>
  3. 4. Challenges for running a wind milll <ul><li>It is unpredictable & intermittent. </li></ul><ul><li>Wind farms occupy large area for producing more power </li></ul><ul><li>Wind turbine can impose adverse impact on envirment </li></ul>
  4. 5. material <ul><li>• cork (at least 2 cm in diameter) </li></ul><ul><li>• DC voltmeter </li></ul><ul><li>• stiff ruler or meter stick or other sturdy wood strip </li></ul><ul><li>• protractor </li></ul><ul><li>• 50 cm of electrical wire with alligator clips </li></ul><ul><li>• rubber bands </li></ul><ul><li>• scotch tape </li></ul><ul><li>• paper clips </li></ul><ul><li>• wire cutters </li></ul><ul><li>• scissors </li></ul><ul><li>• pieces of cardboard </li></ul><ul><li>• cork borer </li></ul><ul><li>• goggles </li></ul>
  5. 6. Material <ul><li>Aluminum sheets: 5 to 7 kg </li></ul><ul><li>Hub </li></ul><ul><li>Main shaft </li></ul><ul><li>Main bearing </li></ul><ul><li>Main clamping unit </li></ul><ul><li>Gear box </li></ul><ul><li>Generator: . Asynchrone generator. Doublegevoed synchron generator. Synchrone generator </li></ul><ul><li>Worm gear </li></ul><ul><li>Multiport worm gear case </li></ul>
  6. 7. Model of wind mill
  7. 8. How Much Power in Moving Air? <ul><li>Power is Energy / Time </li></ul><ul><ul><li>How much Energy in Moving Air </li></ul></ul><ul><ul><li>Kinetic Energy - ½ mv2 </li></ul></ul><ul><ul><li>Power = Energy / Time = .74 Joules /.16 s = 4.6 Watts </li></ul></ul>
  8. 9. <ul><li>Thanks for your patience…. </li></ul>
