Research Abstract |
This report dealt with the experimental and numerical investigations of the effects of 2D contouring, followed by the explanation on the trailing edge reshaping on the loss reduction of a high-lift LPT airfoil. 1. 2D contouring applied in this study was a useful passive device to reduce the cascade loss, especially at low Reynolds number regime. However, such a gain from the device tended to be lost as the Reynolds number increased. 2. TE Reshaping was advantageous for the loss reduction at high Reynolds number regime as designed aiming at the trim of the base region downstream of the trailing edge. 3.The proposed new method in this study, which applies 2D contouring with a smaller step than that of the original one and TE Reshaping at the same time, considerably reduced the cascade loss over the all tested Reynolds number conditions under no incoming wake condition.
