GUEST LECTURE: DAVIDE GATTI Dr.-Ing. Davide Gatti is an Italian researcher in fluid mechanics at the Karlsruhe Institute of Technology. His work focuses on turbulence, drag reduction, and high-performance computing. He earned a PhD with highest honors in 2014 and has since built an international academic career, including research in Japan. He is active as a reviewer, associate editor, and lecturer in advanced fluid mechanics courses, and collaborates with leading universities worldwide. After this course, the students will be able to: • identify the features of a turbulent flows that make their control possible • discuss the conditions that yield to friction drag reduction in turbulent flows • describe the physical working principle of different strategies for skin-friction drag reduction • critically challenge measurement of skin-friction drag reduction

Knowledge of fluid mechanics and turbulence

First, fundamentals of the physics of wall bounded turbulence according to our most up-to-date knowledge will be addressed. Then, the most studied flow control strategies for turbulent friction drag reduction will be introduced and critically analysed. Here, focus will lie on passive method such as riblets, and active methods such as spanwise forcing and wall blowing and suction. The challenges in extending our understanding stemming mostly from simple, canonical flows to complex aerodynamic flows will be discussed. Similarly, challenges in quantifying skin-friction drag reduction both experimentally and numerically will be addressed.
