(2006)This paper deals with a numerical study of classical homogenization of elliptic linear operators with periodic oscillating coefficients (period Y ). The importance of such problems in engineering applications is quite ...
-
(Techno Press, 2019)Copyright © 2019 Techno-Press, Ltd.In this paper a novel and efficient computational framework to estimate the stress range versus number of cycles curves experienced by a cable due to external excitations (e.g., seismic ...
-
(Edizioni ETS, 2018)Numerical prediction of heat transfer by natural convection of a Herschel-Bulkley non-Newtonian fluid inside a square cavity has been computationally analyzed. Unsteady 2D fluid mechanics and heat transfer were described ...
-
(Institute of Mathematical Statistics, 2001-05)We propose a method for numerical approximation of backward stochastic differential equations. Our method allows the final condition of the equation to be quite general and simple to implement. It relies on an approximation of ...
-
(TAYLOR & FRANCIS INC, 2011)In this article we propose a numerical method for reflected backward stochastic differential equations (RBSDE). This method is based on the simple random walk, and the convergence is related to the Skorohod topology.

Numerical methods for elliptic partial differential equations with rapidly oscillating coefficients (2003)This paper presents two methods for the numerical solution of the classical homogenization problem of elliptic operators with periodically oscillating coefficients. The numerical solution of such problems is difficult ...
-
(Springer, 2022)Despite numerous experimental and theoretical studies reported in the literature, surface micro-texturing to control friction and wear in lubricated tribo-contacts is still in the trial-and-error phase. The tribological ...
-
(Universidad de Chile, 2021)The prevention or mitigation of the effects of rockburst in rock masses subjected to high levels of stress, is one of the most challenging problems for the field of study of rock mechanics. Although the use of bolts is a ...
-
(2010)This contribution presents a numerical model of time-dependent physical processes and differentiation in a cooling magma chamber to obtain the magma and liquid composition and model the distribution of minerals and H2O ...
-
(Elsevier, 2020)The development of mining and underground excavations under high stress conditions, where the occurrence of seismic events may induce sudden energy release, has generated new challenges and additional research related to ...
-
(Universidad de Chile, 2020)New technologies related to the mining industry have been developed in the last 50 years as the mining industry has expanded in depth. These technological developments have responded not only to production and planning ...
-
(Springer-Verlag Wien, 2019)© 2018, Springer-Verlag GmbH Austria, part of Springer Nature. In this work, we numerically solve the Brinkman–Darcy equation coupled to the granular kinematic model using the finite elements method in 2D, to describe the ...
-
(Royal Society Publishing, 2018)We provide numerical solutions based on the path integral representation of stochastic processes for nongradient drift Langevin forces in the presence of noise, to follow the temporal evolution of the probability density ...
-
(Universidad de Chile, 2021)This thesis is devoted to the study of inverse problems in a numerical approach. We will focus on problems applied to engineering and science, specifically we will study two problems that we will state below: In the first ...
-
(Elsevier Ltd, 2018)Slurry pipelines transporting a coarse—the comminution product—and a fine fraction, both in the presence of seawater, can cause an alteration of the liquid phase chemical composition. In the present paper, we present ...
-
(Universidad de Chile, 2020)Over the last decades several studies have searched for improved Tube and Fin Heat Exchanger (TFHE) designs capable of providing the best thermohydraulic performance at the lowest possible cost. Such studies have proven ...

Numerical simulation of scour around circular piles due to unsteady currents and oscillatory flows (Taylor & Francis, 2018)Numerical modeling of pile scour is performed due to the action of unsteady currents and oscillatory flow greens, using 3D Reynolds averaged Navier-Stokes (RANS) equations for the hydrodynamic description and the Exner ...
-
(Cambridge University Press, 2015)We report the first simulations of the Faraday instability using the full three-dimensional Navier-Stokes equations in domains much larger than the characteristic wavelength of the pattern. We use a massively parallel code ...

Numerical simulation of tsunami runup in northern Chile based on non-uniform k22 slip distributions (Springer, 2015)A large seismic gap lies along northern Chile and could potentially trigger a M (w) similar to 8.8-9.0 megathrust earthquake as pointed out in several studies. The April 1, 2014, Pisagua earthquake broke the middle segment ...
-
(Elsevier, 2014)The use of computational fluid dynamics gives new and interesting insights for risk analysis of crosscountry ore hydraulic transport operations. In particular, they offer the possibility to predict, with reasonable accuracy, ...
