The objectives of the proposed research include the analysis of the interaction between flowing fluids and oscillating or fixed structures, with applications in aeronautics, heat-exchange equipments, nuclear reactors and other areas of engineering interest. This involves steady and unsteady aerodynamic studies in subsonic, transonic and supersonic regimes and at low Reynolds numbers, with the aim to develop new theoretical and computational methods of solution, which lead to new solutions of the related problems of engineering interest. In addition to the academic interest, these studies aim to provide criteria for the design of improved engineering systems and to contribute with new solutions for important engineering problems, such as flow-induced vibrations and instabilities of engineering systems, structural health monitoring of aircraft and control of aeroelastic oscillations, and unmanned micro-air-vehicles (MAV) design. These require a multi-disciplinary approach involving aerodynamics, structural dynamics, smart materials and micro-electro-mechanical systems (MEMS), as in the previous studies of the applicant. The proposed specific research projects, inter-related in many ways, are:
