Helicoidal particles in turbulent flows with multi-scale helical injection
Luca Biferale, Kristian Gustavsson, Riccardo Scatamacchia
We present numerical and theoretical results concerning the properties of turbulent flows with strong multi-scale helical injection. We perform direct numerical simulations of the…
Cascades and transitions in turbulent flows
A. Alexakis, L. Biferale
Turbulence is characterized by the non-linear cascades of energy and other inviscid invariants across a huge range of scales, from where they are injected to where they are dissipa…
A-priori study of the subgrid energy transfers for small-scale dynamo in kinematic and saturation regimes
Gerardus Petrus Offermans, Luca Biferale, Michele Buzzicotti +1
The statistical properties of the subgrid energy transfers of homogeneous small-scale dynamo are investigated during the kinematic, nonlinear and statistically saturated stages. We…
Multiscale properties of Large Eddy Simulations: correlations between resolved-scale velocity-field increments and subgrid-scale quantities
Moritz Linkmann, Michele Buzzicotti, Luca Biferale
We provide analytical and numerical results concerning multi-scale correlations between the resolved velocity field and the subgrid-scale (SGS) stress-tensor in large eddy simulati…
Effects of thermal fluctuations in the fragmentation of a nano-ligament
Xiao Xue, Mauro Sbragaglia, Luca Biferale +1
We study the effects of thermally induced capillary waves in the fragmentation of a liquid ligament into multiple nano-droplets. Our numerical implementation is based on a fluctuat…
Multiscale velocity correlations in turbulence and Burgers turbulence: Fusion rules, Markov processes in scale, and multifractal predictions
Jan Friedrich, Georgios Margazoglou, Luca Biferale +1
We compare different approaches towards an effective description of multi-scale velocity field correlations in turbulence. Predictions made by the operator product expansion, the s…
On the inverse energy transfer in rotating turbulence
M. Buzzicotti, P. Clark Di Leoni, L. Biferale
Rotating turbulence is an example of a three-dimensional system in which an inverse cascade of energy, from the small to the large scales, can be formed. While usually understood a…
Inferring flow parameters and turbulent configuration with physics-informed data-assimilation and spectral nudging
P. Clark Di Leoni, A. Mazzino, L. Biferale
Inferring physical parameters of turbulent flows by assimilation of data measurements is an open challenge with key applications in meteorology, climate modeling and astrophysics.…
Equivalence of nonequilibrium ensembles in turbulence models
Luca Biferale, Massimo Cencini, Massimo De Pietro +2
Understanding under what conditions it is possible to construct equivalent ensembles is key to advancing our ability to connect microscopic and macroscopic properties of non-equili…
Rayleigh-Taylor turbulence with singular nonuniform initial conditions
Luca Biferale, Guido Boffetta, Alexei A. Mailybaev +1
We perform direct numerical simulations of three dimensional Rayleigh-Taylor turbulence with a nonuniform singular initial temperature background. In such conditions, the mixing la…
Non-universal behaviour of helical two-dimensional three-component turbulence
Moritz Linkmann, Michele Buzzicotti, Luca Biferale
The dynamics of two-dimensional three-component (2D3C) flows is relevant to describe the long-time evolution of strongly rotating flows and/or of conducting fluids with a strong me…
Time irreversibility in reversible shell models of turbulence
Massimo De Pietro, Luca Biferale, Guido Boffetta +1
Turbulent flows governed by the Navier-Stokes equations (NSE) generate an out-of-equilibrium time irreversible energy cascade from large to small scales. In the NSE, the energy tra…
