Navier-stokes analysis of airfoils with Gurney flap [PDF]

, 2006
Two dimensional steady state Navier-Stokes computations were performed to determine the effect of Gurney flap on NACA 4412 and NACA 0011 airfoils. Gurney flap sizes selected for the study range from 0.5% to 4% of the airfoil chord.

Gurney flap對垂直軸風力機氣動力之影響

, 1969
碩士隨著全世界科技的進步，人口的上升，能源耗盡成為我們重視的議題。因此取之不盡用之不竭的再生能源成為大家近期所研究的對象，其中風力發電是一種不錯的再生能源。風力發電可分為水平式與垂直式兩種風力機，吾人在此研究中所探討的是單片翼型為NACA4412之葉片的垂直式風力機進行模擬。進而加裝Gurney flap，進行探討加裝置在模擬過後的氣動力分析是否能改善其葉片轉動的效能。在數值分析中，使用二階精確浸入邊界法來了解Gurney如何影響升力垂直軸風力發電機。我們模擬測試使用流速為U = 1 m ...
