20.500.12556/RUL-158326 Numerical modelling of continuous casting of round billets with turbulence in the melt The present work aims to solve the continuous casting benchmark problem in axisymmetry with turbulence in the melt by the meshless method. The physical model of the liquid-solid system that involves mass, momentum and energy conservation is formulated in the mixture continuum approximation. The melt is assumed Newtonian and incompressible. A k-epsilon Reynolds averaged Navier-Stokes turbulence model is implemented with Abe-Kondoh-Nagano closures. The mushy region is modelled as a Darcy porous media with the Kozeny-Carman permeability model. The solution of partial differential equations is implemented locally using collocation with radial basis functions and explicit time-stepping. The velocity pressure coupling is performed using the fractional step method. The validation of the model is assessed by comparing its outcomes with the results of the finite volume method. A sensitivity study of the varying casting speed and temperature on the velocity, temperature, and solid fraction fields is shown. continuous casting of steel CFD turbulence modeling meshless methods kontinuirno ulivanje jekla računalniška dinamika tekočin modeliranje turbulence brezmrežna metoda true false true Angleški jezik Slovenski jezik Neznano 2024-06-05 13:17:00 2024-06-05 13:17:08 2025-04-21 11:45:50 0000-00-00 00:00:00 2024 0 0 6 str.
