description La presente investigación se centra en el estudio numérico del movimiento de partículas no esféricas regulares que caen libremente en un fluido newtoniano inicialmente en reposo. La base del método numérico se centró en el uso de la técnica PR-DNS (Particle Resolved Direct Numerical Simulation) con la combinación de técnicas de mallas superpuesta para la discretización del dominio fluido y el solucionador SixDOF como fundamento para el enfoque lagrangiano que permita determinar el movimiento y la trayectoria de la partícula a partir del cálculo de las fuerzas y momentos que actúan sobre la superficie de la partícula. El diseño de los modelos geométricos fue desarrollado en Solidworks y las simulaciones numéricas se llevaron a cabo empleando técnicas avanzadas de dinámica de fluidos computacional en el módulo ANSYS Fluent. Se desarrollaron las simulaciones transitorias bajo diferentes combinaciones tanto para partículas 2D como tridimensionales. Las primeras simulaciones se llevaron a cabo para un ejemplo popular de prueba numérica que describe el flujo 2D causado por la caída libre de una partícula circular dentro de un depósito líquido, así como mediciones experimentales 3D en la sedimentación de una esfera, las cuales fueron verificadas y validadas con estudios numéricos y experimentales previos, mostrando una alta fiabilidad en la descripción del movimiento de este tipo de formas. Se encontró que las partículas circulares y esféricas bajo las condiciones de estudio utilizadas, describen regímenes de movimiento considerados como verticalmente estables, al no presentar cambios repentinos en la trayectoria de caída ni desplazamientos laterales considerables. Se demostró que la dinámica de las inestabilidades de la trayectoria se caracterizarse por el triplete (Γ,Ga,χ ) correspondiente a la relación de la densidad sólido/líquido, el número de Galileo y la relación de aspecto. A partir de este punto se desarrolló una serie de simulaciones numéricas para analizar la sedimentación de elipses y elipsoides oblatos para complementar el análisis y conocer los alcances del método numérico. Los resultados demostraron la gran dependencia de la trayectoria a los parámetro relevantes y la incidencia de la relación de aspecto. Se encontró diferentes modos para el régimen oscilatorio de las elipses influenciado por la relación de aspecto que al aumentar no solo influye en la aparición de nuevos modos de movimiento oscilatorio si no que retrasa el tiempo de asentamiento de las partículas. Este estudio, en concordancia con los objetivos planteados, propone un nuevo método para analizar la dinámica de asentamiento de diferentes tipos de partículas. También ayuda a ampliar la gama de escenarios y combinaciones de parámetros para enriquecer el análisis de la dinámica de partículas no esféricas regulares e irregulares que aún no han sido desarrolladas.

La base del método numérico se centró en el uso de la técnica PR-DNS (Particle Resolved Direct Numerical Simulation) con la combinación de técnicas de mallas superpuesta para la discretización del dominio fluido y el solucionador SixDOF como fundamento para el enfoque lagrangiano que permita determinar el movimiento y la trayectoria de la partícula a partir del cálculo de las fuerzas y momentos que actúan sobre la superficie de la partícula. El diseño de los modelos geométricos fue desarrollado en Solidworks y las simulaciones numéricas se llevaron a cabo empleando técnicas avanzadas de dinámica de fluidos computacional en el módulo ANSYS Fluent. Se desarrollaron las simulaciones transitorias bajo diferentes combinaciones tanto para partículas 2D como tridimensionales. Las primeras simulaciones se llevaron a cabo para un ejemplo popular de prueba numérica que describe el flujo 2D causado por la caída libre de una partícula circular dentro de un depósito líquido, así como mediciones experimentales 3D en la sedimentación de una esfera, las cuales fueron verificadas y validadas con estudios numéricos y experimentales previos, mostrando una alta fiabilidad en la descripción del movimiento de este tipo de formas. Se encontró que las partículas circulares y esféricas bajo las condiciones de estudio utilizadas, describen regímenes de movimiento considerados como verticalmente estables, al no presentar cambios repentinos en la trayectoria de caída ni desplazamientos laterales considerables. Se demostró que la dinámica de las inestabilidades de la trayectoria se caracterizarse por el triplete (Γ,Ga,χ ) correspondiente a la relación de la densidad sólido/líquido, el número de Galileo y la relación de aspecto. A partir de este punto se desarrolló una serie de simulaciones numéricas para analizar la sedimentación de elipses y elipsoides oblatos para complementar el análisis y conocer los alcances del método numérico. Los resultados demostraron la gran dependencia de la trayectoria a los parámetro relevantes y la incidencia de la relación de aspecto. Se encontró diferentes modos para el régimen oscilatorio de las elipses influenciado por la relación de aspecto que al aumentar no solo influye en la aparición de nuevos modos de movimiento oscilatorio si no que retrasa el tiempo de asentamiento de las partículas. Este estudio, en concordancia con los objetivos planteados, propone un nuevo método para analizar la dinámica de asentamiento de diferentes tipos de partículas. También ayuda a ampliar la gama de escenarios y combinaciones de parámetros para enriquecer el análisis de la dinámica de partículas no esféricas regulares e irregulares que aún no han sido desarrolladas.This research focuses on the numerical study of the motion of regular non-spherical particles falling freely in a stagnant Newtonian fluid initially at rest. The basis of the numerical method focused on the use of the PR-DNS (Particle Resolved Direct Numerical Simulation) technique with the combination of overlapping mesh techniques for the discretization of the fluid domain and the SixDOF solver as the basis for the Lagrangian approach to determine the motion and trajectory of the particle from the calculation of the forces and moments acting on the surface of the particle. The design of the geometric models was developed in Solidworks and the numerical simulations were carried out using advanced computational fluid dynamics techniques in the ANSYS Fluent module. Transient simulations were developed under different combinations for both 2D and 3D particles. The first simulations were carried out for a popular numerical test example describing the 2D flow caused by the free fall of a circular particle inside a liquid tank, as well as 3D experimental measurements on the sedimentation of a sphere, which were verified and validated with previous numerical and experimental studies, showing a high reliability in the description of the motion of this type of shapes. It was found that the circular and spherical particles under the study conditions used, describe motion regimes considered as vertically stable, since they do not present sudden changes in the fall trajectory or considerable lateral displacements. It was shown that the dynamics of the trajectory instabilities are characterized by the triplet (Γ,Ga,χ ) corresponding to the solid/liquid density ratio, the Galileo number and the aspect ratio. From this point, a series of numerical simulations were developed to analyze the sedimentation of ellipses and oblate ellipsoids to complement the analysis and to know the scopes of the numerical method. The results demonstrated the strong dependence of the trajectory on the relevant parameters and the incidence of the aspect ratio. Different modes were found for the oscillatory regime of the ellipses influenced by the aspect ratio which, when increasing, not only influences the appearance of new modes of oscillatory motion but also delays the settling time of the particles. This study, in agreement with the stated objectives, proposes a new method to analyze the settling dynamics of different types of particles. It also helps to extend the range of scenarios and parameter combinations to enrich the analysis of the dynamics of regular and irregular non-spherical particles that have not yet been developed.Tesis (Magister en Sistemas Energéticos)-- Universidad Autónoma de Occidente, 2024MaestríaMagíster en Sistemas Energéticos94 páginasapplication/pdfspaUniversidad Autónoma de OccidenteMaestría en Sistemas EnergéticosFacultad de IngenieríaCaliDerechos reservados - Universidad Autónoma de Occidente, 2024https://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessAtribución-NoComercial-SinDerivadas 4.0 Internacional (CC BY-NC-ND 4.0)http://purl.org/coar/access_right/c_abf2Simulación Numérica Directa de la deposición de partículas no esféricas en grandes contenedoresTrabajo de grado - MaestríaTextinfo:eu-repo/semantics/masterThesishttp://purl.org/redcol/resource_type/TMinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85Alger, G.
