Nonlinear fokker-planck equation for an overdamped system with drag depending on direction
(Multidisciplinary Digital Publishing Institute, 2021-09)
We investigate a one-dimensional, many-body system consisting of particles interacting via repulsive, short-range forces, and moving in an overdamped regime under the effect of a drag force that depends on direction. That ...
Drag force in a strongly coupled anisotropic plasma
(SPRINGERNEW YORK, 2012)
We calculate the drag force experienced by an in finitely massive quark propagating at constant velocity through an anisotropic, strongly coupled N = 4 plasma by means of its gravity dual. We find that the gluon cloud ...
A Reynolds stress model for turbulent flows of viscoelastic fluids
(Taylor & Francis Ltd, 2013-12-01)
A second-order closure is developed for predicting turbulent flows of viscoelastic fluids described by a modified generalised Newtonian fluid model incorporating a nonlinear viscosity that depends on a strain-hardening ...

Preferential Concentration of Free-Falling Heavy Particles in Turbulence
(American Physical Society, 2020-08)
We present a sweep-stick mechanism for heavy particles transported by a turbulent flow under the action of gravity. Direct numerical simulations show that these particles preferentially explore regions of the flow with ...
Properties of the body of a turbidity current at near‐normal conditions: 2. Effect of settling
(Blackwell Publishing, 2019-11)
Turbidity currents are sediment-laden flows that move over a sloping surface. These flows are driven by the density difference between the sediment-laden current and the clear ambient fluid above. Here we focus on studying ...
Pressure center determination for regularly shaped non-spherical particles at intermediate Reynolds number range
(Elsevier, 2021)
The present contribution aims to determine the dependence of the location of the non-dimensional center of pressure ( with orientation () for non-spherical particles of regular shape. Prolate and oblate ellipsoids as well ...
New developments in isotropic turbulent models for FENE-P fluids
(2018-01-29)
The evolution of viscoelastic turbulent models, in the last years, has been significant due to the direct numeric simulation (DNS) advances, which allowed us to capture in detail the evolution of the viscoelastic effects ...
Acoustoelectric drag current in vanadium oxide films
(American Physical Society, 2020)
Two different Mott insulator wires, vanadium dioxide and vanadium sesquioxide, were prepared on the piezoelectric LiNbO3 substrates. Coupling of acoustic waves propagating in LiNbO3 with free carriers in vanadium oxide ...
