Abstract

The use of wavy leading and trailing edges is presented in the literature as a possible method for improving the aerodynamic characteristics of a wing. However, the results available in the literature provide only a fragmented understanding of this problem, and therefore there are a lot of research possibilities in this topic. Considering this, these flow control mechanisms will be studied as part of the joint PhD program between University of São Paulo and Imperial College London, using direct numerical simulations and stability analysis techniques. The simulations will employ the Spectral Element Method, available through the Nektar++ project, and will be performed at low Reynolds numbers, allowing the study of the transition of the flow to a three-dimensional regime. An infinite wing will be analyzed in the first place, and then the study will be extended to the three-dimensional case, where the planform of the wing becomes relevant. (AU)
