(Iop publishing LTD, 2018-05)It has been shown that self-assembled chains of active colloidal particles can present sustained oscillations. These oscillations are possible because the effective diffusiophoretic forces that mediate the interactions of ...
-
(Universidad de Chile, 2008)En este trabajo presentamos un nuevo algoritmo para simulación de medios granulares densos que incluye partículas estáticas en presencia de gravedad. El modelo consiste en esferas duras inelásticas, para el cual contamos ...
-
(ELSEVIER, 2006-09-15)We consider a non-interacting one-dimensional gas accelerated by a constant and uniform external field. The energy absorbed from the field is transferred via elastic collisions to a bath of scattering obstacles. At ...
-
(Universidad de Chile, 2011)El objetivo general del presente trabajo es encontrar una relación experimental que defina la condición límite en que las partículas pertenecientes a un lecho, por sobre el cual se tiene un flujo de un fluido no newtoniano, ...
-
(Royal Society of Chemistry, 2020)We confine a dense suspension of motileEscherichia coliinside a spherical droplet in a water-in-oil emulsion, creating a "bacterially" propelled droplet. We show that droplets move in a persistent random walk, with a ...
-
(Elsevier Ltd, 2019)A discrete element method is designed to evaluate the relative wear on hoppers caused by friction during operation in an open-pit mine. The results of the model show good agreement with measurements on real industrial ...
-
(American Physical Society, 2014)We show that the Casimir effect can emerge in microswimmer suspensions. In principle, two effects conspire against the development of Casimir effects in swimmer suspensions. First, at low Reynolds number, the force on ...
-
(American Institute of Physics Inc., 1998)We present the microscopic description of the vapor using the concept of cluster. Taking into consideration nonideal contributions, the distribution functions of every cluster species are obtained. From these distribution ...
-
(American Physical Society, 2016)The emergence of clustering and coarsening in crowded ensembles of self-propelled agents is studied using a lattice model in one dimension. The persistent exclusion process, where particles move at directions that change ...
-
(AMER INST PHYSICS, CIRCULATION & FULFILLMENT DIV, 2006-08)The collective dynamics of a quasi-two-dimensional suspension jet, of non-Brownian particles, confined in a thin cell and driven by gravitational force is studied both numerically and theoretically. We present a theoretical ...
-
(Universidad de ChileCyberDocs, 2010)La mayoría de los flujos granulares densos en la naturaleza, tales como avalanchas de detritos, flujos piroclásticos, deslizamientos de tierra y avalanchas subacuáticas, están constituidos por una amplia gama de diferentes ...
-
(Amer Physical SOC, 2018)The critical phenomena associated to the liquid-to-solid transition of quasi-two-dimensional vibrated granular systems is studied using molecular dynamics simulations of the inelastic hard sphere model. The critical ...
-
(Universidad de Chile, 2012)En esta tesis se presenta el estudio de suspensiones pasivas de esferas microm ́etri- cas y suspensiones activas de bacterias tipo Escherichia coli sometidas a un cizalle simple en el l ́ımite de bajo nu ́mero de Reynolds. ...
-
(Universidad de Chile, 2014)En esta tesis se diseñó e implementó una metodología experimental a escala microfluídica, enfocada al estudio de la difusión en redes cuasi-bidimensionales aleatorias de microcanales. Para ello, se adaptó la técnica de la ...
-
(American Physical Society, 2014)Agranular system confined in a quasi-two-dimensional box that is vertically vibrated can transit to an absorbing state in which all particles bounce vertically in phase with the box, with no horizontal motion. In principle, ...
-
(Amer Assoc Advancement Science, 2020)One notable feature of bacterial motion is their ability to swim upstream along corners and crevices, by leveraging hydrodynamic interactions. This motion through anatomic ducts or medical devices might be at the origin ...

(Universidad de Chile, 2012)Un baño bacteriano consiste en un fluido en el que nadan bacterias. Este nado produce agitaciones en el sistema, induciendo un campo de velocidades en él. En esta tesis, se presenta un estudio hidrodinámico de las ...
-
(Royal Soc., 2015)We describe the collective behaviour of a system of many inelastic spherical particles inside a box which is being periodically vibrated. The box is shallow, with large horizontal dimensions, while the height is less than ...
-
(Amer Physical Soc, 2018)Granular systems confined in vertically vibrated shallow horizontal boxes (quasi-two-dimensional geometry) present a liquid-to-solid phase transition when the frequency of the periodic forcing is increased. An effective ...
