Palestra Especial

Introduction to turbulence and blow up
Uriel Frisch

Laboratoire Lagrange, Observatoire and Universite Cote d'Azur Nice, France
Terça-feira, 15 de maio de 2018, 14:00
Auditorio 1

This lecture is intended to give a rough idea of some of questions arising in turbulence: Reynolds number and instabilities, chaos and the butterfly effect, fully developed turbulence as a spatial variant of Brownian motion, fractals in Nature and in turbulence, simple models leading to finite time explosion (blow-up), nonlinear depletion and possible avoidance of blow-up.

The lecture will be elementary and accessible to students whose background is in mathematics, or physics, or engineering or numerical analysis.
