Diffusion in fluid flows
Enhancement of diffusion and reaction processes by advection is a classical
subject that has been extensively studied by both physicists and
mathematicians. In this talk I will consider reaction-diffusion on a
bounded domain in the presence of a fast incompressible flow. I will also
consider convective systems in a bounded domain, in which viscous fluids
described by the Stokes system are coupled using the Boussinesq
approximation to a reaction-advection-diffusion equation for the
temperature.
