本研究針對風機模型及透孔盤於均勻流中進行尾流逐點量測，並藉由分析其推力係數、速度分布、紊流強度等氣動力特性來探討風機模型於不同翼尖速度比下之尾流特性差異及發展與透孔盤在不同透孔率下之尾流氣動力特性差異及發展情況。
推力係數之計算方法以動量理論及圓盤理論計算得到，且以50%透孔率之透孔盤驗證準確性。根據結果顯示，透孔盤於50%透孔率下之推力係數約為0.61。而本研究之風機模型於翼尖速度比為1.88時有最大推力係數，約0.124。
此研究量測風機模型與單一透孔盤之尾流截面速度分布，對於風機模型以比較不同翼尖速度比下之不同截面尾流特性差異與尾流發展為主，而透孔盤則以兩種透孔率比較不同截面尾流特性差異與尾流發展為主，進而得出以透孔盤模擬風機之概念。

This research is experimented by measuring every point behind the model wind turbine and the porous disk under the uniform freestream flow condition and is analyzing the aerodynamic characteristics including thrust coefficient, velocity distribution and turbulence intensity to discuss wake characteristics and its development for the model wind turbine under different tip speed ratio and the porous disk under different porosity.
The thrust coefficient is calculated by momentum theorem and actuator disc theorem and this method is proved by the porous disk in fifty percent. The result show that the thrust coefficient of the porous disk in fifty percent is about 0.61 and of the model wind turbine in tip speed ratio equals to 1.88 found is maximum about 0.124.
Another work is to measure the sectional velocity of the model wind turbine and the single porous disk. The wake characteristics and development compared under different tip speed ratio for the model wind turbine and with two kind of porosity for the porous disk. Finally, there is a concept of simulating the model wind turbine with the porous disk.
