A Lagrangian stochastic model of a volcanic eruption column
Benjamin J. Devenish, Matteo Cerminara
We develop a Lagrangian stochastic model (LSM) of a volcanic plume in which the mean flow is provided by an integral plume model of the eruption column and fluctuations in the vert…
Multi-particle dispersion in fully developed turbulence
L. Biferale, G. Boffetta, A. Celani +3
The statistical geometry of dispersing Lagrangian clusters of four particles (tetrahedra) is studied by means of high-resolution direct numerical simulations of three-dimensional h…
Lagrangian statistics of particle pairs in homogeneous isotropic turbulence
L. Biferale, G. Boffetta, A. Celani +3
We present a detailed investigation of the particle pair separation process in homogeneous isotropic turbulence. We use data from direct numerical simulations up to Taylor's Reynol…
Acceleration and vortex filaments in turbulence
F. Toschi, L. Biferale, G. Boffetta +3
We report recent results from a high resolution numerical study of fluid particles transported by a fully developed turbulent flow. Single particle trajectories were followed for a…
Multifractal statistics of Lagrangian velocity and acceleration in turbulence
L. Biferale, G. Boffetta, A. Celani +3
The statistical properties of velocity and acceleration fields along the trajectories of fluid particles transported by a fully developed turbulent flow are investigated by means o…
