Sokol A. Mathematical models of multiphase environments dynamics in a converter at blowing through multinozzle tuyer.

In this work the results of theoretical researches of hydrodynamic processes in a multiphase environment, flowings in the cavity of converter during blowing out of melt by an overhead multinozzle tuyer are presented. The quasi-three-dimensional mathematical model of multiphase environment dynamics is created. It describes processes, flowings in the cavity of converter during blowing out of melt by an overhead multinozzle tuyer. The proper software which will realize the built mathematical model and allows to conduct numerical experiment with the different values of technological parameters is created. For the construction of isosurfaces created the module, which realizing the method so-called "Marching Cubes". By software numerical experiments are conducted, their results are analysed. The three-dimensional mathematical model of dynamics of multiphase environment in the cavity of converter is first created. It is based on that geometrical part, what quasi-three-dimensional model. In a difference from quasi-three-dimensional model the equations of three-dimensional mathematical model decide in the three-dimensional raising. The proper software which will realize the built mathematical model is created. By software numerical experiments are conducted, their results are compared. The ways of improvement of the created mathematical models are outlined. Keywords: converter, hydrodynamic processes, mathematical model, boundary condition, calculation area, numerical experiment.
