Force measurement results from this study have revealed that the degree of performance enhancement possible for an airfoil with tubercles is not significantly influenced by three-dimensional effects at Reynolds number, Re = 120,000. Therefore, based on the present results and the available literature, it is postulated that the effectiveness of tubercles as a passive flow control mechanism is more dependent on the Reynolds number than on three-dimensional effects.
