SUMMARY:Edriss Titi\, University of Cambridge and Texas A&M University
STATUS:CONFIRMED
DESCRIPTION:Turbulence is a classical physical phenomenon that has been a g
reat challenge to mathematicians\, physicists\, engineers and computationa
l scientists. In the end of the last century\, chaos theory was developed
to explore similar phenomena that occur\nin a wide range of applied scienc
es\, but the eyes have always been on the big ball – Turbulence. Control
ling and identifying the onset of turbulence have a great economic and ind
ustrial impact ranging from reducing the drag on cars and commercial airpl
anes to better design of fuel engines\, weather and climate predictions.\n
It is widely accepted by the scientific community that turbulent flows are
governed by the Navier-Stokes equations\, for large Reynolds numbers. As
such\, the Navier-Stokes equations form the main building block in any flu
id model\, in particular in global climate models. Whether the solutions t
o the three-dimensional Navier-Stokes equations remain smooth\, indefinite
ly in time\, is one of the most challenging mathematical problems.\n It wa
s identified by the Clay Institute of Mathematics as one of the seven most
outstanding Millennium Problems in mathematics\, and it has set a $1 mill
ion prize for solving it. In this talk I will describe\, using layman lang
uage\, the main challenges that the different scientific communities are f
acing while attempting\nto attack this problem. In particular\, I will emp
hasize the mathematical point of view of turbulence.
