Abstract A 3-D mathematical model based on collocated grid is built in order to investigate the transient flow in the continuous casting mold using large eddy simulation. The model can perform the spatial discretization for non-orthogonal hexahedral elements of mesh. QUICK scheme with deferred correction is adopted when discretizating the convection term in momentum equation in order to increase the stability of the code. Block-structured grid is adopted when meshing the computational domain. The transient flow field in the mold is investigated. The results indicate that the flow is unsteady and asymmetric. The nozzle jet swings periodically, and the upper recirculation zone center as well as the wave height change periodically. These transient phenomena are interrelated.
