"Heat Rises: Convection, Stability, and Turbulence"

Charles R. Doering
Department of Mathematics, Department of Physics,

Rayleigh-Bénard convection is the buoyancy-driven flow that results
when a fluid is heated from below and cooled from above sufficiently
to destabilize the conduction state where the fluid is at rest. A key
experimental, theoretical, and mathematical challenge is to ascertain
the functional dependence of the heat transport on the applied
temperature drop and on the material parameters characterizing the
fluid. Turbulent convection is of particular interest. In this talk
we will review some of the history and scientific applications of
Rayleigh-Bénard convection, describe some theory and analysis
connecting notions of nonlinear stability to the statistical dynamics
of the highly unstable turbulent regime, and compare the results with
direct numerical simulations and laboratory experiments.
