Strains and Jets in Black Hole Fields
D. Bini, F. de Felice, A. Geralico
We study the behaviour of an initially spherical bunch of particles emitted along trajectories parallel to the symmetry axis of a Kerr black hole. We show that, under suitable cond…
Modeling the pressure Hessian and viscous Laplacian in Turbulence: comparisons with DNS and implications on velocity gradient dynamics
L. Chevillard, C. Meneveau, L. Biferale +1
Modeling the velocity gradient tensor A along Lagrangian trajectories in turbulent flow requires closures for the pressure Hessian and viscous Laplacian of A. Based on an Eulerian-…
Parallel multiscale modeling of biopolymer dynamics with hydrodynamic correlations
Maria Fyta, Jayanta Sircar, Efthimios Kaxiras +3
We employ a multiscale approach to model the translocation of biopolymers through nanometer size pores. Our computational scheme combines microscopic Molecular Dynamics (MD) with a…
Conservation laws with vanishing nonlinear diffusion and dispersion
Philippe G. LeFloch, Roberto Natalini
We study the limiting behavior of the solutions to a class of conservation laws with vanishing nonlinear diffusion and dispersion terms. We prove the convergence to the entropy sol…
Acceleration of heavy and light particles in turbulence: comparison between experiments and direct numerical simulations
R. Volk, E. Calzavarini, G. Verhille +4
We compare experimental data and numerical simulations for the dynamics of inertial particles with finite density in turbulence. In the experiment, bubbles and solid particles are…
Spin-rotation couplings: spinning test particles and Dirac field
Donato Bini, Luca Lusanna
The hypothesis of coupling between spin and rotation introduced long ago by Mashhoon is examined in the context of "1+3" and "3+1" space-time splitting techniques, either in specia…
Dimensionality and morphology of particle and bubble clusters in turbulent flow
Enrico Calzavarini, Martin Kerscher, Detlef Lohse +1
We conduct numerical experiments to investigate the spatial clustering of particles and bubbles in simulations of homogeneous and isotropic turbulence. Varying the Stokes parameter…
Two-Dimensional Fluctuating Vesicles in Linear Shear Flow
Reimar Finken, Antonio Lamura, Udo Seifert +1
The stochastic motion of a two-dimensional vesicle in linear shear flow is studied at finite temperature. In the limit of small deformations from a circle, Langevin-type equations…
Capillary filling using Lattice Boltzmann Equations: the case of multi-phase flows
F. Diotallevi, L. Biferale, S. Chibbaro +5
We present a systematic study of capillary filling for multi-phase flows by using mesoscopic lattice Boltzmann models describing a diffusive interface moving at a given contact ang…
Polynomial functors and opetopes
Joachim Kock, André Joyal, Michael Batanin +1
We give an elementary and direct combinatorial definition of opetopes in terms of trees, well-suited for graphical manipulation and explicit computation. To relate our definition t…
Discreteness effects in a reacting system of particles with finite interaction radius
Stefano Berti, Cristobal Lopez, Davide Vergni +1
An autocatalytic reacting system with particles interacting at a finite distance is studied. We investigate the effects of the discrete-particle character of the model on propertie…
Large deviations of Poisson cluster processes
Charles Bordenave, Giovanni Luca Torrisi
In this paper we prove scalar and sample path large deviation principles for a large class of Poisson cluster processes. As a consequence, we provide a large deviation principle fo…
Multiscale modeling of biopolymer translocation through a nanopore
Maria Fyta, Simone Melchionna, Efthimios Kaxiras +1
We employ a multiscale approach to model the translocation of biopolymers through nanometer size pores. Our computational scheme combines microscopic Langevin molecular dynamics (M…
Exploring DNA translocation through a nanopore via a multiscale Lattice-Boltzmann Molecular-Dynamics methodology
Simone Melchionna, Maria Fyta, Efthimios Kaxiras +1
A multiscale approach is used to simulate the translocation of DNA through a nanopore. Within this scheme, the interactions of the molecule with the surrounding fluid (solvent) are…
Multiscale coupling of molecular dynamics and hydrodynamics: application to DNA translocation through a nanopore
Maria G. Fyta, Simone Melchionna, Efthimios Kaxiras +1
We present a multiscale approach to the modeling of polymer dynamics in the presence of a fluid solvent. The approach combines Langevin Molecular Dynamics (MD) techniques with a me…
