报告简介：
Scientists and Engineers face the challenge to develop novel technologies optimally exploiting sustainably generated energy to answer the urgent need for sustainable development. At the same time existing technology, concepts, and designs need to be pushed to their limits in terms of energy efficiency, minimal use of resources (material) and minimum impact on the environment (emissions, noise). As a result of these developments design and development require an integrated view on both the large scale functionality such as aerodynamics and blade or wing design for wind turbines and aircraft, as well controlling the small scale noise sources in the flow. Similarly, aerodynamic power optimization can not be separated from reliability determined by the small lubricant films in bearings. Current aircraft design consists mainly of small step evolution. To face the challenges of the future truly disruptive new designs are needed where propulsion is often distributed and more integrated in the aircraft structure. As a results physics, mechanics, fluid/aerodynamics aspects of design, which could be often studied separately, need to be studied in much closer collaboration between scientists and engineers of different disciplines. The Engineering Fluid Dynamics group at the University of Twente, is built on this vision and has developed into a strong interdisciplinary group with a rich high level research portfolio. In this lecture an overview is given of achievements in different fields such as aerodynamics/aeroacoustics, fluid mechanics of function materials, thin layer flows and lubrication, are presented, each contributing steps towards a more sustainable future.
