20.500.12556/DKUM-67160 Lagrangian particle tracking in velocity-vorticity resolved viscous flows by subdomain BEM A numerical study of particle motion in a cubic lid driven cavity is presented. As a computational tool, a boundary element based flow solver with a Lagrangian particle tracking algorithm is derived. Flow simulations were performed using an in-house boundary element based 3D viscous flow solver. The Lagrangian particle tracking algorithm is capable of simulation of dilute suspensions of particles in viscous flows taking into account gravity, buoyancy, drag, pressure gradient and added mass. The derived algorithm is used to simulate particle behaviour in a cellular flow field and in a lid driven cavity flow. Simulations of particle movement in a cellular flow field were used to validate the algorithm. The main goal of the paper was to numerically simulate the flow behaviour of spheres of different densities and different diameters, as experimentally observed in work of Tsorng et al.The study of slightly buoyant and non-buoyant particles in a lid driven cavity was aimed at discovering cases when particles leave the primary vortex and enter into secondary vortices, a phenomenon described in the work of Tsorng et al. A parametric study of this phenomenon was preformed. The presented computational results show excellent agreement with experiments, confirming the accuracy of the developed computational method. dispersed two phase flow Lagrangian particle tracking cellular flow lid driven cavity boundary element method mehanika tekočin magnetna sila hidrodinamična sila metoda robnih elementov true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-04 09:34:54 2017-08-04 09:35:41 2022-08-01 13:37:16 2019-07-11 16:11:03 2016 0 0 str. 1533-1549 št. 3 Letn. 9 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1735-3572 519.61/.64:532.72 19549974 19552022 1735-3572 URN:SI:UM:DK:1GC8RNPV Journal_of_Applied_Fluid_Mechanics_2016_Ravnik,_Hriberŝek,_Lupŝe_Lagrangian_particle_tracking_in_velocity-vorticity_resolved_viscous_flo.pdf Journal_of_Applied_Fluid_Mechanics_2016_Ravnik,_Hriberŝek,_Lupŝe_Lagrangian_particle_tracking_in_velocity-vorticity_resolved_viscous_flo.pdf 1 162B9900B598DCAE81D2DA29ED1AE5CC c86e9c5aa0a1fe9b52352bf6c8ee388b0b3da8e8ad2619d9b22b0f0343ffc4b5 7a728efd-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/308aa75b-bd69-4963-b44a-ae59498c2080 https://dk.um.si/Dokument.php?lang=slv&id=114842 http://jafmonline.net/web/guest/home?p_p_id=JournalArchive_WAR_JournalArchive_INSTANCE_nvhn&p_p_action=0&p_p_state=maximized&p_p_mode=view&_JournalArchive_WAR_JournalArchive_INSTANCE_nvhn_form_page=main_form&selectedVolumeId=68&selectedIssueId=228 1 https://dk.um.si/Dokument.php?lang=slv&id=114841 Fakulteta za strojništvo 0 0 0
