Ion transfer across liquid|liquid interface under forced hydrodynamic conditions. I: Digital simulations
(Elsevier Science Sa, 2012-02)
In this paper, we present the general equations for a model that describes ion transfer reactions across the oil|water interface assisted by a ligand, under forced hydrodynamic conditions. Our analysis is mainly focused ...
Dynamic simulation and optimisation of tubular polymerisation reactors in gPROMS
(Pergamon-Elsevier Science Ltd, 2001-05-12)
In this paper a dynamic model of the high-pressure polymerisation of ethylene in tubular reactors is introduced and a dynamic optimisation problem is formulated for studying start-up strategies. The optimisation objectives ...
Monte Carlo simulation with fixed steplength for diffusion processes in nonhomogeneous media
(Academic Press Inc Elsevier Science, 2013-04)
Monte Carlo simulation is one of the most important tools in the study of diffusion processes. For constant diffusion coefficients, an appropriate Gaussian distribution of particle's steplengths can generate exact results, ...
Modelling and Simulation of Drag Forces of Non-spherical Particles Moving Towards a Surface in Polymer Melt Flows
(Elsevier Science, 2017-07)
This work deals with the drag forces acting on non-spherical particles translating normal to a surface in a polymer melt in which the particle–surface distance is small compared with particle dimension in the flow direction. ...
Simulating Web Search Engines
(IEEE Computer Society, 2017-01)
A simulation methodology is proposed to evaluate the performance of large-scale Web search engines hosted by datacenters. The salient features of the methodology are the use of models of parallel computing to overcome the ...
Interventions to reduce verocytotoxigenic Escherichia coli in ground beef in Argentina: A simulation study
(Elsevier Science, 2010-04)
A stochastic simulation model was used to assess the effects of measures implemented in the agri-food-chain to reduce the contamination of ground beef with verotoxigenic Escherichia coli (VTEC). A published risk assessment ...
Monte Carlo simulations for understanding the transport properties of metallic nanowires
(Elsevier Science, 2020-10)
We report the conductance calculation of metallic nanowires of different metals under the application of a tensile force. The elongation induced by the tensile force was simulated by means of the canonical Monte Carlo ...
Computer simulation of reversible electrochemical catalyst promoter dosing
(Pergamon-Elsevier Science Ltd, 2010-12)
Grand Canonical Monte Carlo simulations were used to study the growth of a Na layer onto a O-p(2 × 2)-Pt(1 1 1) surface. At the beginning of the deposition, the film presents a disordered structure which becomes progressively ...
Electrodeposition in highly viscous media: Experiments and simulations
(Elsevier Science, 2009-07)
Electrolyte viscosity plays an important role in ion transport. Here we study the effects of high viscosity variations in thin-layer electrochemical deposition (ECD) under constant-current conditions through experimental ...
