Characterisation of pneumatic conveying systems using the Euler/Lagrange approach
Laín Beatove, Santiago; Sommerfeld, Martin (Elsevier BV, 2013-02)This paper deals with the transport of solid particles in pneumatic conveying systems, namely a 5 m horizontal pipe, a 90° bend and 5 m a vertical pipe. The pipe diameter is 150 mm in all cases and the average conveying ... -
Computational methods. Euler-lagrange methods
Sommerfeld, Martin; Lain, Santiago (2016-10)The Eulerian approach for the particles considers cellaveraged particle characteristics based on the continuous-phase grid nodes. This approach is efficient in terms of predicting particle concentration. Lagrangian Particle ... -
Derivation and validation of a hard-body particle-wall collision model for non-spherical particles of arbitrary shape
Quintero Arboleda, Brian; Laín Behatove, Santiago; Sommerfeld, Martin (Elsevier, 2021-03)In this work an extended three-dimensional model to describe the process of wall collisions of arbitrary shaped non-spherical particles is developed. This model is derived as the generalized solution of the hard-sphere ... -
Effect of geometry on flow structure and pressure drop in pneumatic conveying of solids along horizontal ducts
Laín Beatove, Santiago; Sommerfeld, Martin (Researchgate, 2011-02)Este estudio presenta nuevos desarrollos en el enfoque de Euler / Lagrange para calcular flujos confinados cargados de partículas en líneas de transporte neumático. Se hace especial hincapié en la influencia de las colisiones ... -
Influence of droplet collision modelling in Euler/Lagrange calculations of spray evolution
Sommerfeld, Martin; Lain, Santiago (ResearchGate, 2020-07)The numerical computation of spraying systems is favourably conducted by applying the Euler/Lagrange approach. Although sprays downstream of the breakup region are very often rather dilute, droplet collisions may still ... -

Laín Beatove, Santiago; Sommerfeld, Martin (Universidad Autónoma de Occidente, 2007-01)El presente estudio analiza la pérdida de presión en el flujo gas-sólido que se desarrolla en un canal horizontal de sección rectangular desde los puntos de vista experimental y numérico. Tanto los experimentos como los ... -
Parameters influencing dilute‐phase pneumatic conveying through pipe systems: a computational study by the Euler/Lagrange approach
Lain Beatove, Santiago; Sommerfeld, Martin (2014-11)The present contribution summarizes research related to the numerical computation of pneumatic conveying systems applying the Euler/Lagrange approach. For that purpose, a rigorous modelling of the particulate phase was ... -
Prediction of horizontal gas–solid flows under different gravitational fields
Laín Beatove, Santiago; Sommerfeld, Martin (Elsevier, 2014)In this paper the performance of horizontal pneumatic conveying under different gravity environments is evaluated. An Euler–Lagrange approach validated versus ground experiments is employed to predict the relevant particle ... -
Pressure center determination for regularly shaped non-spherical particles at intermediate Reynolds number range
Castang Montiel, Carlos Eduardo; Laín Behatove, Santiago; Sommerfeld, Martin (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 ... -

El esquema de simulación combina el método de Simulación de Grandes ... -
Stochastic modelling for capturing the behaviour of irregular-shaped non-spherical particles in confined turbulent flows
Lain, Santiago; Sommerfeld, Martin (Elsevier, 2018-03-15)For calculating dispersed particle-ladenflows in confined systems, the well-known Euler/Lagrange approach ismost suitable. Lagrangian tracking of non-spherical particles with certain shapes is mostly performed by addi-tionally ... -
Study of colliding particle-pair velocity correlation in homogeneous isotropic turbulence
Ernst, Martin; Sommerfeld, Martin; Lain, Santiago (MDPI, 2020-12-19)This paper deals with the numerical analysis of the particle inertia and volume fraction effects on colliding particle-pair velocity correlation immersed in an unsteady isotropic homogeneous turbulent flow. Such correlation ... -
Transport characteristics of isometric non-spherical particles in turbulent flows
Laín Beatove, Santiago; Sommerfeld, Martin (Universidad Autónoma de Occidente, 2008-01)Este artículo estudia las características principales del transporte de partículas no esféricas isométricas, con diferentes grados de esfericidad, en un flujo turbulento. La fracción de carga másica de partículas es ...
