Seminar "Transition to turbulence in pipe flow" by Prof. Dr. Marc Avila


2023年6月27日 (火) 16:30 17:30





Prof. Dr. Marc Avila

Director ZARM - Center of Applied Space Technology and Microgravity,

Professor of Fluid Mechanics,

University of Bremen, Germany



Flows through pipes undergo a sudden transition from laminar to turbulent motion as the fluid velocity increases. Understanding this transition has occupied engineers, physicists and mathematicians alike since Reynolds’ ground-breaking experiments in the nineteenth century. In this talk, I will review the recent progress on this problem from three distinct perspectives: (i) hydrodynamic stability, (ii) phase transitions and (iii) dynamical systems. Similarities to other wall-bounded flows and outstanding open points will be discussed.  Special attention will be paid to the mechanisms of turbulence relaminarization and its prediction.
