COMPARISON OF AERODYNAMICS CHARACTERISTICS OF NACA 0015 & NACA 4415 AEROFOIL BLADE

摘要: NACA 0015 and 4415 aerofoil are most common four digits broadly used aerodynamic shape. Both of the shapes extensively for various kind applications including turbine blade, aircraft wing so on. is symmetrical unsymmetrical in Consequently, they have big one-of-a-kind traits at side widespread differences their utility performance. them undergo same fluid principle while applied any medium giving dissimilar outcomes aerodynamics behavior. On this work, experimental numerical investigation each done to decide For purpose, section tested a prevalence range attack angle (AOA). The study addresses performance evaluates dynamics flow separation, lift, drag, pressure velocity contour
