Surface light modulation by sea ice and phytoplankton survival in a convective flow model
Vinicius Beltram Tergolina, Enrico Calzavarini, Gilmar Mompean +1
Plankton dynamics depend in a complex manner on a variety of physical phenomena, according to both experimental and numerical data. In particular, experimental field studies have h…
Effects of large-scale advection and small-scale turbulent diffusion on vertical phytoplankton dynamics
Vinicius Beltram Tergolina, Enrico Calzavarini, Gilmar Mompean +1
Turbulence has been recognized as a factor of paramount importance for the survival or extinction of sinking phytoplankton species. However, dealing with its multiscale nature in m…
Elastic turbulence in two-dimensional cross-slot viscoelastic flows
Dário Oliveira Canossi, Gilmar Mompean, Stefano Berti
We report evidence of irregular unsteady flow of two-dimensional polymer solutions in the absence of inertia in cross-slot geometry using numerical simulations of Oldroyd-B model.…
Beyond the maximum drag reduction asymptote: the pseudo-laminar state
Anselmo Pereira, Roney L. Thompson, Gilmar Mompean
Recent experiments indicated that polymers can reduce the turbulent drag beyond the asymptotic limit known as the MDR, leading to a laminar flow. In this Letter, we show through di…
Particle-laden two-dimensional elastic turbulence
Himani Garg, Enrico Calzavarini, Gilmar Mompean +1
The aggregation properties of heavy inertial particles in the elastic turbulence regime of an Oldroyd-B fluid with periodic Kolmogorov mean flow are investigated by means of extens…
An objective perspective for classic flow classification criteria
Ramon S. Martins, Anselmo S. Pereira, Gilmar Mompean +2
Four classic criteria used to the classification of complex flows are discussed here. These criteria are useful to identify regions of the flow related to shear, elongation or rigi…
Finite Volume Streaming-based Lattice Boltzmann algorithm for fluid-dynamics simulations: a one-to-one accuracy and performance study
Kalyan Shrestha, Gilmar Mompean, Enrico Calzavarini
A new finite volume (FV) discretisation method for the Lattice Boltzmann (LB) equation which combines high accuracy with limited computational cost is presented. In order to assess…
