Mixing and enhanced dissipation in a time-translating shear flow
Johannes Benthaus, Giuseppe Maria Coclite, Camilla Nobili
Motivated in part by the work of Vanneste and Byatt-Smith, we study mixing and enhanced dissipation for the advection-diffusion equation with velocity field $\mathbf{u}(x,y,t)=(\si…

Enhanced Dissipation via time-modulated velocity fields
Johannes Benthaus, Camilla Nobili
Motivated by mixing processes in analytical laboratories, this work investigates enhanced dissipation in non-autonomous flows. We study the evolution of concentrations governed by…
