Meshless approach to the large-eddy simulation of the continuous casting process

The paper discusses the numerical solution of large-eddy formulation for modelling turbulent fluid flow with solidification in continuous casting steel. This industrially relevant problem is solved by a meshless method first time. solid-liquid system formulated within continuum mixture governing, mass momentum and energy equations. Darcy porous media model describes mushy region. based on Smagorinsky sub-grid scale viscosity van Driest damping function. synthetic turbulence prescribed at molten steel inlet. generated fluctuations are isotopic correlated time through an asymmetric filter. Explicit discretisation, combined local radial basis function collocation method, employed. Five-noded subdomains, non-uniform node arrangement multiquadrics shape functions used solving two-dimensional model. sensitivity to different arrangements, steps, inlet temperature, velocity boundary conditions elaborated successfully verified comparison our previously published k − ε same process.
