Abstract:

I will discuss recent results on speed-up of reaction-diffusion traveling fronts by strong flows. I will present a characterization of those periodic flows which can arbitrarily speed up fronts for general combustion-type reactions in two dimensions, and the rate of this speed-up will also be determined. The problem turns out to be closely connected to the simpler question of effective diffusivity enhancement in the corresponding (linear) passive scalar model.
