This bilateral project tackles critical challenges in noise reduction and aerodynamic efficiency for the aerospace and wind energy industries. It investigates two key phenomena: Shock Wave/Boundary Layer Interaction (SWBLI) in high-speed flows, which leads to total pressure losses, increased drag, and noise; and trailing-edge noise in airfoils.

While passive flow control methods have been studied before, serrated trailing edges remain largely unexplored in high-speed regimes. Similarly, while perforated plates are known to influence SWBLI, their combined application with advanced serrations on high-speed components like rotor tips and centrifugal compressor vanes represents a novel, unified approach that merges aerodynamic optimization with aeroacoustic analysis.

The project’s core objectives are to optimize the geometry and material application of perforated plates and serrated edges, validate their performance through real-world experiments, and identify their ideal placement on airfoils. Using a combination of Computational Fluid Dynamics (CFD) simulations and advanced wind tunnel testing at various flow regimes, the project aims to significantly improve SWBLI control and achieve effective noise reduction.

Beyond its technical goals, this collaboration is a powerful capacity-building initiative for Moldovan scientists. They will gain hands-on exposure to advanced aerodynamic infrastructure alongside the renowned Romanian team, which possesses deep expertise in subsonic to supersonic flow regimes. By engaging Moldovan researchers as co-authors in high-impact publications and expanding their scientific visibility, the project not only supports innovative research in aerospace and sustainable energy but also positions Moldovan experts to lead future international projects.
