本課程將使學生瞭解機翼如何有升力的產生,以及翼形彎度和攻角對翼形壓力分佈所產生的影響。課程內容亦包含流體運動方程式、邊界層效應(層流、流場分離、過渡至紊流),以及阻力產生等。 This course will provide students with an understanding of how lift is produced by an airfoil, and the effect of airfoil camber and angle of attack on the pressure distribution about an airfoil. Discussions also include the equations of motion for a fluid, basic behaviors of boundary layers (from laminar flow, flow separation, and transition to turbulence), and drag production.
