中文摘要 | 本研究分別採用動態數值模擬與風洞實驗方法,在不同飛行條件下,針對類蜻蜓翼 型拍翼式微飛行器之各種氣動力係數進行分析與驗證。在數值模擬部分主要以ANSYS ICEM/CFD 建構翼翅表面與翼翅周圍計算域動態網格,搭配ANSYS FLUENT 計算流體 力學(CFD)軟體與使用者自訂函數介面(UDF),模擬飛行時各種飛行姿態並求得氣動力 係數;在風洞實驗部份,將依數值分析結果製作之類蜻蜓翼型拍翼式微飛行器實體模 型,利用開放式低速風洞進行風洞實驗,並完成氣動力分析與流場可視化研究,最後將 兩者所得數據進行比對,以證明本研究所採用之數值及實驗平台具有可行性與良好的可 靠度。 |
英文摘要 | In this study, dynamic numerical simulation and wind tunnel experiments was used to solve and verify various aerodynamic characteristics for the dragonfly-like wings type flapping MAVs in different flight conditions. The meshes of computing zone are built by using conformal hybrid mesh and dynamic mesh with C programming language, and these meshes are useful in modeling 3-D trajectory of dragonfly-like flapping wings. In addition, commercial CFD software ANSYS FLUENT with user-defined function (UDF) to complete the aerodynamic coefficients in various flight attitude. In wind tunnel experiments, the dragonfly-like wings type flapping MAVs are practically fabricated in this dissertation. This study use of the open low-speed wind tunnel, complete aerodynamic characteristics analysis and flow field visualization. Finally, both the data for comparison, to prove that the numerical and experimental platform used in this study the feasibility and reliability. |
