Stochastic modeling of Fourier modes in two-dimensional turbulence via filtered white noise
Paolo Cifani, Franco Flandoli, Andrea Zanoni
Modeling turbulent flows by a random Fourier decomposition is a classical procedure in order to use simplified models of turbulence in heat transport and other applications. We inv…
Anomalous diffusion properties of stochastic transport by heavy-tailed jump processes
Paolo Cifani, Franco Flandoli, Lorenzo Marino
In this work, we investigate the large-scale transport properties of a passive scalar advected by a turbulent fluid, modelled as a superposition of divergence-free vector fields, e…
An efficient geometric method for incompressible hydrodynamics on the sphere
Paolo Cifani, Milo Viviani, Klas Modin
We present an efficient and highly scalable geometric method for two-dimensional ideal fluid dynamics on the sphere. The starting point is Zeitlin's finite-dimensional model of hyd…
