Universal Velocity Profile for Coherent Vortices in Two-Dimensional Turbulence
M. Chertkov, I. Kolokolov, V. Lebedev
Two-dimensional turbulence generated in a finite box produces large-scale coherent vortices coexisting with small-scale fluctuations. We present a rigorous theory explaining the $η…
Strong effect of weak diffusion on scalar turbulence at large scales
M. Chertkov, I. Kolokolov, V. Lebedev
Passive scalar turbulence forced steadily is characterized by the velocity correlation scale, , injection scale, , and diffusive scale, . The scales are well separated i…
Decay of scalar turbulence revisited
M. Chertkov, V. Lebedev
We demonstrate that at long times the rate of passive scalar decay in a turbulent, or simply chaotic, flow is dominated by regions (in real space or in inverse space) where mixing…
Pulse confinement in optical fibers with random dispersion
M. Chertkov, I. Gabitov, J. Moeser
Short range correlated uniform noise in the dispersion coefficient, inherent in many types of optical fibers, broadens and eventually destroys all initially ultra-short pulses. How…
