本研究將利用振盪U-型管,使管內水柱上下擺盪,而管內利用Gorlov (1998)開發成的螺旋形葉片水渦輪(Gorlov Helical Turbine),來研究及探討發電技術。此U-型管受外力作用下管內水柱上下運動造成管內流體左右振盪,並帶動管內水渦輪轉動,進而帶動發電機發電。本文中利用田口方法找出此發電系統最佳尺寸及發電量,並製作U-型管發電系統模型與前人實際量測數據做驗證,實驗結果發現田口方法與實際量測數據的最佳尺寸相符合。
藉由試驗結果比對發現,管中流體振盪頻率和葉片面積率確實會影響結構系統的發電量,當外力週期在共振頻率範圍附近時發電效果更好。
This research will use a vibrating U-tube which will cause the water around the tube sway in but will manage the helix leaf blade water turbine which (1998) will develop using Gorlov (Gorlov Helical Turbine). It will also study and discuss electricity generating technology. The vertical motion created external force under the U-tube and about the water will cause the fluid to vibrate and lead the tube cause the domestic water turbine to rotate thus generating electricity. In this article discovers the best size for a generating system and the power rate using the Taguchi method and manufactures the U-tube generating system model and the predecessor gauges the data to make the confirmation, the experimental result discovered the Taguchi method and the actual gauging data best tallies the size.
The test results show that in the tube, the fluid oscillation frequency and the blade area rate can affect the structure of the system as well as the true power rate while the external force cycle resonance frequency scope generates electricity.
