TRR 181 Seminar "Dynamical-system approach to the turbulence problem”
The TRR 181 seminar is held every two weeks in the semester and as announced during semester break. The locations of the seminar changes between the three TRR181 locations, but is broadcasted online for all members of the TRR.
The TRR 181 seminar is held by Marc Avila (head of ZARM) on
Dynamical-system approach to the turbulence problem
at the University of Bremen, MZH 4140 on Tuesday, February 22th at 10:00.
*Abstract*
Fluid flows through pipes are ubiquitous in engineering because of their simplicity, but a theory for the emergence of turbulence in pipes has challenged generations of scientists and engineers. In this talk I will give a brief perspective of hydrodynamic stability and will show how complex dynamics emerges in pipe flow via simple solutions of the governing equations. The results reveal surprising similarities between transition in linearly stable and unstable flows and highlight the applicability of dynamical-system approaches to wide classes of flows. Open challenges and hopeless goals will be discussed.
