| description abstract | Rotating machinery plays a preponderant role in most of the industrial sectors, including, but not limited to, energy production and storage, automobile, maritime transport, aviation, and aerospace. Since the first development of the water wheel a few thousand years ago, modern rotating machines have been developed during the past century for various applications, as rocket engine turbopumps, hydraulic and gas turbines, marine propellers, compressors, turbochargers, ventilators and blowers, marine and wind turbines. Despite the high level of efficiency and reliability of these systems, major innovations and developments are still present in the area of rotating machinery. Current challenges concern noise reduction, notably in the field of aviation, low-carbon power generation through the development of new renewable energy technologies (e.g., wind and marine energy) and the improvement of the efficiency of existing technologies, improvement of the flexibility and reliability of rotating machines in off-design operations where they may face aggressive flows and instabilities. Addressing all these issues requires skills in various fields, including combustion, heat transfer, fluid-structure interaction, multiphase flow, aero-acoustics and hydro-acoustics, rotor dynamic, advanced optimization. In addition, the increasing complexity of industrial systems and technologies, together with the new requirement in term of industry decarbonization, make the optimization of rotating machinery and the understanding and control of internal flows more and more challenging, requiring the development of ground-breaking advanced numerical modeling and experimental techniques. | |
