Multiscale Mixing Efficiencies for Steady Sources
Charles R. Doering, Jean-Luc Thiffeault
Multiscale mixing efficiencies for passive scalar advection are defined in terms of the suppression of variance weighted at various length scales. We consider scalars maintained by…

Low-wavenumber forcing and turbulent energy dissipation
Charles R. Doering, Nikola P. Petrov
A popular method of forcing the fluid in Direct Numerical Simulations of turbulence is to take the body force proportional to the projection of the velocity of the fluid onto its l…

Extinction times for birth-death processes: exact results, continuum asymptotics, and the failure of the Fokker-Planck approximation
Charles R. Doering, Khachik V. Sargsyan, Leonard M. Sander
We consider extinction times for a class of birth-death processes commonly found in applications, where there is a control parameter which determines whether the population quickly…
