Abstract: The implementation of Co-Flow Jet (CFJ) concept on low Reynolds number airfoil FX63-137 had been studied both numerically and experimentally. The experimental study has shown that it does not always give better performance in comparison with that of suction or jet injection only. To use CFJ concept effectively, the momentum coefficient is found to be in the range of 5% to 13%. When the momentum coefficient is less than 5%, the use of suction alone is recommended, while for the momentum coefficient is higher than 13%, the implementation of jet injection alone is a better option. Furthermore, the use of smaller size of jet injection slot demonstrates better performance in CFJ system. In conjunction with the use of smaller slot size of jet injection, the location of the suction slot located further upstream in the vicinity of the onset of separated flow, would gives better results in suppressing separated flow and enhancing lift than that located further downstream. © 2010 by Temasek Laboratories, National University of Singapore.
