20.500.12556/DiRROS-18503 Meshless simulation of a macrosegregation benchmark considering the solid motion We have extended the existing two-dimensional rigid solid phase benchmark for binary substance with the solid phase motion in the present paper. Incompressible laminar Newtonian flow is assumed, and a standard mixture formulation is used for the mass, momentum, energy, and solute transport. A coherency solid motion model accounts for the free-floating grains, assuming that the solid velocity is proportional to the mixture velocity and the liquid fraction. The lever rule is used to describe the mass fractions of the phases. A two-dimensional benchmark is solved using the semi-implicit meshless diffuse approximate method with an adaptive subdomain upwinding strategy. The results of the meshless method are compared to the finite volume method results with a reasonable agreement. The new benchmark results show that the solid motion has an essential effect on the macrosegregation pattern. solidification meshless methods grain motion benchmarks strjevanje brezmrežne metode gibanje zrn testni primeri true false true IOP Publishing Anglija Angleški jezik Slovenski jezik Neznano 2024-03-21 08:38:14 2024-03-21 08:38:14 2024-05-20 14:24:26 0000-00-00 00:00:00 2023 0 0 Številka članka: 012039; Str. 1-8 Vol. 1281 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.61 1757-8981 10.1088/1757-899X/1281/1/012039 153238787 153238531 https://iopscience.iop.org/article/10.1088/1757-899X/1281/1/012039 1 fb80525b-e755-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25211 RAZ_Govze_Viktor_2023.pdf RAZ_Govze_Viktor_2023.pdf 1 819543765D60D36413BDE671C35B9282 4a2d60e28ef5243d58296830618a13c5f10c005436a27c2f6d90b0caf82f67e0 5be89e3e-e757-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25213 Inštitut za kovinske materiale in tehnologije 0 0 0
