20.500.12556/DKUM-96561 Mass distribution impacts on particle translation and orientation dynamics in dilute flows We present a novel model for tracking particles (based on Lagrangian particle tracking) with inhomogeneous mass distribution. Without loss of generality, the presented approach captures inhomogeneity by assuming an offset spherical inclusion in an elongated ellipsoidal particle matrix. The model is first validated on simplified flow configurations such as particles settling in vacuum or air as well as suspended in simple shear and laminar pipe flow, where we achieved an excellent agreement with the available reference results. Furthermore, we investigate the impact of the inclusion parameters on the particle motion. Finally, the deposition of inhomogeneous particles in a simplified bifurcation is analyzed. We conclude that the consideration of inhomogeneity significantly alters the translational and orientational dynamics of the particles. Consequently, we advocate for the consideration of more realistic mass distributions to increase the accuracy of modeling and predicting the motion of inhomogeneous particles in flows for real-world applications. inhomogeneous particles spherical inclusion Lagrangian particle tracking particle deposition prenos snovi sledenje delcem nehomogeni delci Lagrangeovo sledenje delcev true false true Elsevier Angleški jezik Slovenski jezik https://www.sciencedirect.com/journal/powder-technology © 2025 The Authors Članek v reviji 2026-01-19 14:37:03 2026-01-19 14:37:04 2026-01-20 03:18:50 0000-00-00 00:00:00 2025 0 0 str. 1-18; [article no.] 120424 Vol. 452 Feb. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-07-08 2024-11-02 2024-11-13 532 220397315 10.1016/j.powtec.2024.120424 1873-328X 1-s2.0-S0032591024010684-main.pdf 1-s2.0-S0032591024010684-main.pdf 1 6BBD8300A30D7290517CADF59CD1387E c02d64a33e881db4ab5a04f1210bbf7180ee74a4f136acac3145e6cbfd842d69 690b9e31-f53c-11f0-94a4-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=202179 https://www.sciencedirect.com/science/article/pii/S0032591024010684?via%3Dihub 1 efb42e83-f53b-11f0-94a4-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=202177 Fakulteta za strojništvo 0 0 0
