How winding is the coast of Britain ? Conformal invariance of rocky shorelines
G. Boffetta, A. Celani, D. Dezzani +1
We show that rocky shorelines with fractal dimension 4/3 are conformally invariant curves by measuring the statistics of their winding angles from global high-resolution data. Such…
Condensation of cloud microdroplets in homogeneous isotropic turbulence
Alessandra S. Lanotte, Agnese Seminara, Federico Toschi
The growth by condensation of small water droplets in a three-dimensional homogeneous isotropic turbulent flow is considered. Within a simple model of advection and condensation, t…
Large-scale anisotropy in scalar turbulence
Antonio Celani, Agnese Seminara
The effect of anisotropy on the statistics of a passive tracer transported by a turbulent flow is investigated. We show that under broad conditions an arbitrarily small amount of a…
The large-scale structure of passive scalar turbulence
Antonio Celani, Agnese Seminara
We investigate the large-scale statistics of a passive scalar transported by a turbulent velocity field. At scales larger than the characteristic lengthscale of scalar injection, y…
