Synthetic Lagrangian Turbulence by Generative Diffusion Models

1 code implementation17 Jul 2023 Tianyi Li, Luca Biferale, Fabio Bonaccorso, Martino Andrea Scarpolini, Michele Buzzicotti

Lagrangian turbulence lies at the core of numerous applied and fundamental problems related to the physics of dispersion and mixing in engineering, bio-fluids, atmosphere, oceans, and astrophysics.

Generative Adversarial Networks to infer velocity components in rotating turbulent flows

no code implementations18 Jan 2023 Tianyi Li, Michele Buzzicotti, Luca Biferale, Fabio Bonaccorso

We perform a systematic quantitative benchmark of point-wise and statistical reconstruction capabilities of the linear Extended Proper Orthogonal Decomposition (EPOD) method, a non-linear Convolutional Neural Network (CNN) and a Generative Adversarial Network (GAN).

Taming Lagrangian Chaos with Multi-Objective Reinforcement Learning

no code implementations19 Dec 2022 Chiara Calascibetta, Luca Biferale, Francesco Borra, Antonio Celani, Massimo Cencini

We consider the problem of two active particles in 2D complex flows with the multi-objective goals of minimizing both the dispersion rate and the energy consumption of the pair.

Structure and Isotropy of Lattice Pressure Tensors for Multi-range Potentials

2 code implementations26 Sep 2020 Matteo Lulli, Luca Biferale, Giacomo Falcucci, Mauro Sbragaglia, Xiaowen Shan

We systematically analyze the tensorial structure of the lattice pressure tensors for a class of multi-phase lattice Boltzmann models (LBM) with multi-range interactions.

Flow Navigation by Smart Microswimmers via Reinforcement Learning

no code implementations30 Jan 2017 Simona Colabrese, Kristian Gustavsson, Antonio Celani, Luca Biferale

Smart active particles can acquire some limited knowledge of the fluid environment from simple mechanical cues and exert a control on their preferred steering direction.
