PACM Colloquium: Survival and Schooling Hydrodynamics

Mon, Feb 13, 2017, 4:00 pm

The aqueous environment of natural swimmers mediates magnificent patterns of schooling as well as their escape and attack routines. We study the fluid mechanics of single and multiple swimmers through simulations that rely on state of the art multi-resolution vortex methods. Stochastic optimisation and  machine learning algorithms are used to find optimal shapes and motions for single and synchronised patterns for multiple swimmers. I will discuss how the orchestration of body deformations and vortex dynamics can result in thrust and energy savings for these artificial swimmers and juxtapose these findings with swimming patterns of natural organisms. Lessons learned can assist the design and operation of energy efficient swimming devices.

Petros Koumoutsakos is Full Professor of Computational Science at ETH Zurich since 2000. He received his Diploma (1986) in Naval Architecture at the National Technical University of Athens and a Master’s (1987) at the University of Michigan, Ann Arbor. He received his Master’s (1988) in Aeronautics and his PhD (1992) in Aeronautics and Applied Mathematics from the California Institute of Technology. He is Fellow of the American Society of Mechanical Engineers, the American Physical Society and the Society of Industrial and Applied Mathematics. He is  recipient  of the ACM Gordon Bell prize in Supercomputing and the Advanced Investigator Award by the European Research Council (2013). He is presently a Fellow at the Radcliffe Institute of Advanced Study at Harvard University and at the Collegium Helveticum in Zurich.
