Droplet size distribution in homogeneous isotropic turbulence
Prasad Perlekar, Luca Biferale, Mauro Sbragaglia +2
We study the physics of droplet breakup in a statistically stationary homogeneous and isotropic turbulent flow by means of high resolution numerical investigations based on the mul…
Unified framework for a side-by-side comparison of different multicomponent algorithms: lattice Boltzmann vs. phase field model
Luca Scarbolo, Dafne Molin, Prasad Perlekar +3
Lattice Boltzmann Models (LBM) and Phase Field Models (PFM) are two of the most widespread approaches for the numerical study of multicomponent fluid systems. Both methods have bee…
Convection in multiphase flows using Lattice Boltzmann methods
L. Biferale, P. Perlekar, M. Sbragaglia +1
We present high resolution numerical simulations of convection in multiphase flows (boiling) using a novel algorithm based on a Lattice Boltzmann method. We first validate the ther…
Cumulative compressibility effects on population dynamics in turbulent flows
Prasad Perlekar, Roberto Benzi, David R. Nelson +1
Bacteria and plankton populations living in oceans and lakes reproduce and die under the in- fluence of turbulent currents. Turbulent transport interacts in a complex way with the…
Dynamic Multiscaling in Two-dimensional Fluid Turbulence
Samriddhi Sankar Ray, Dhrubaditya Mitra, Prasad Perlekar +1
We obtain, by extensive direct numerical simulations, time-dependent and equal-time structure functions for the vorticity, in both quasi-Lagrangian and Eulerian frames, for the dir…
