Abstract

In order to calculate the hydrodynamic characteristics during the steel casting into the "liquid" crystallizer, the differential equation of the boundary layer was solved at the initial stage, as a result of which a solution was obtained at the interface of two parallel flows. The parameters of the laminar boundary layer are calculated at the interface between two immiscible liquids, when moving in a concurrent flow. The dimensional thickness of the boundary layer is calculated when steel casting in a "liquid" crystallizer. A mathematical model for the distribution of the velocity profile in a laminar layer at the interface of two flows is composed. Estimates of the dimensional thickness of the boundary layer as a function of the ratio of the velocities of steel and coolant motion are established, it is established that, depending on the ratio of velocities, they can be in a rather wide range of values: at and the dimensional thickness of the boundary layer is within .
