The spatio-temporal spectrum of turbulent flows
(Springer, 2015-12)
Identification and extraction of vortical structures and of waves in a disorganised flow is a mayor challenge in the study of turbulence. We present a study of the spatio-temporal behavior of turbulent flows in the presence ...
Analysis of the velocity field of granular hopper flow
(Granular Matter, 2018)
Environmental studies in two communes of Santiago de Chile by the analysis of magnetic properties of particulate matter deposited on leaves of roadside trees
(Elsevier Ltd, 2017)
© 2016 The Authors Emissions from motor vehicles are considered to be one of the main sources of airborne particulate matter in Santiago. International researchers have shown that particulate matter contains metal oxides ...
Heat transfer enhancement in a channel with a built-in rectangular cylinder
(Springer-Verlag, 1995)
A two dimensional numerical investigation of the unsteady laminar flow pattern and forced convective heat transfer in a channel with a built-in rectangular cylinder is presented. The channel in the entrance region has a ...
Forced flow of granular media: Breakdown of the Beverloo scaling
(Europhysics Letters, 2018-08)
The Beverloo scaling for the gravity flow of granular materials through orifices has two distinct universal features. On the one hand, the flow rate is independent of the height of the granular column. On the other hand, ...
Segregation in a model system for tapped wet disks in two dimensions
(Springer, 2015-11-30)
The problem of segregation of mixtures in a column of wet disks subjected to tapping is studied through a simple model that simulates, through a pseudo-dynamics algorithm, the formation of the packing and the successive ...
Granular flow through an aperture: Pressure and flow rate are independent
(American Physical Society, 2011-06)
We simultaneously measure the flow rate and the normal force on the base, near the outlet, during the discharge through an orifice of a dense packing of monosized disks driven by a conveyor belt. We find that the normal ...
Riemann-Christoffel flows
(Springer/plenum PublishersNew YorkEUA, 2008)
Splitting up dark matter
(Universidad de San Andrés. Departamento de Economía, 2021-11)
This paper offers a detailed analysis of an alternative measure of income flows from officials’ accounts denominated
“dark matter.” We aim to extend this area of investigation by splitting dark matter into two main ...
Mixed brush of chemically and physically adsorbed polymers under shear: Inverse transport of the physisorbed species
(American Institute of Physics, 2014-01)
We study mixed brushes under shear flow by molecular dynamics simulation with an explicit solvent. The primary brush is formed by chemically grafting polymers to a solid substrate, the secondary brush is comprised of ...
