Analysis Seminar

Separation of time-scales in fluid mechanics

Speaker: Michele Coti-Zelati, Imperial College

Location: Warren Weaver Hall 1302

Date: Thursday, October 3, 2019, 11 a.m.

Synopsis:

We present recent results on time-scales separation in fluid
mechanics. The fundamental mechanism to detect in a precise
quantitative manner is commonly referred to as fluid mixing. Its
interaction with advection, diffusion and nonlocal effects produces a
variety of time-scales which explain many experimental and numerical
results related to hydrodynamic stability and turbulence theory.
