Development of Three-Dimensional LES Based Meshless Model of Continuous Casting of Steel

A large-eddy simulation (LES) based meshless model is developed for the three-dimensional (3D) problem of continuous casting (CC) steel billet. The local collocation method on radial basis functions (RBF) applied in 3D. applies scaled multiquadric (MQ) RBF with a shape parameter seven nodded sub-domains. incompressible turbulent fluid flow described using mass, energy, and momentum conservation equations LES turbulence model. solidification system solved mixture continuum Boussinesq approximation buoyancy Darcy porous media are used. Chorin’s fractional step used to couple velocity pressure. microscopic closed lever rule compared two-equation Low Re k?? Reynolds Averaged Navier–Stokes (RANS) terms temperature, computational times. resolves transient character vortices which RANS-type models unable tackle. cost considerably higher than RANS. On other hand, it results much lower direct numerical (DNS). paper demonstrates ability solve realistic industrial 3D examples. Trivial adjustment nodal densities, high accuracy, low diffusivity main advantages this method.
