dc.description.abstract | 由於綠能的崛起,相對的帶動風能產業發展。風力發電機也往高容量持續發展,但在追求高容量的同時,我們時常面對風力發電機實際發出效率達不到所設計之目標值。
本文就以一商用額定功率為2KW小型風力發電機作為探討對象,評估其風力發電機的效益。以實際葉片作為分析對象,需先進行掃描葉片用來建構其模型,再進行CFD數值分析。本文利用商用軟體作為模擬,先利用Gambit前處理器進行邊界、流場設定,再使用Fluent求解器進行求解分析。本文先針對實際葉片之原始裝置角進行分析,再對其設計不同裝置旋轉角度,因而產生不同扭矩,再經過計算探討其葉片運轉效率之變化。第二部份,在探討效率變化的同時,也對葉片結構應力進行分析。本文在結構方面,是使用Ansys workbench 12.0進行分析。在流場分析時,我們可得知在不同裝置角度會產生不同的壓力負載,再將其邊界條件匯至結構上進行分析,以進一步比較、評估當在提升效率的同時,其葉片結構上的變化。 | zh_TW |
dc.description.abstract | Since the rise of green energy, the industry of wind energy has been developed relatively. And now the wind turbine capacity also expanded, but when we pursuit of high-capacity, we often face that the real produce of the efficiency of wind turbines didn’t reach the design of target values.
In this article a 2kW rate power wind turbines blade has been use to simulate the blade’s efficiency. Firstly, built up its model by using a three-coordinate infrared ray’s measuring machine scanner to scan the blade’s geometry and then analyze the blade by computational fluid dynamics. Two commercial simulation software has been used to solve the dynamic fluid problem. Preprocessor – Gambit to set boundary and flow field, and then using the solver of Fluent to estimate the blade’s relevant parameters. In the simulation, several pitch angles has been investigate besides the original angle of the blade. The alteration of pitch angel will produce different torque; therefore, the blade’s efficiency has been change. Due to the magnitude of the pressure side and the suction side of the blade vary with the pitch angle by transferring the pressure data and boundary conditions in fluent to Ansys workbench 12.0 to investigate the blade structural stress. | en |
