Summary

The subject continues on the subject Modeling and visualization of metallurgical processes and deepens the theoretical knowledge and practical skills in numerical modelling of metallurgical processes. The attention is focused on the study of steel flow in metallurgical reactors using numerical simulation in ANSYS FLUENT solver and the study of solidification of steel in environment simulation software QuikCAST.

Subject syllabus:

1. Modeling flow in flow metallurgical reactors – examples of modeling of steel flow in the tundish, of steel flow in subentry nozzles, in the initial stages of filling of the bottom casting into ingots. Identification of the nature of the flow. Steady and unsteady flow conditions. Modelling of turbulent flow. . 2. Description of simulated area - the geometry of symmetric and asymmetric objects. The selection of the density and type of computational mesh. Boundary Conditions - Flow Boundary Conditions (velocity inlet, pressure inlet, mass flow inlet, pressure outlet, outflow). Determination of parameters of turbulence. 3. Definitions and modification of material properties. Using the definition of physical properties such as temperature-dependent function. Thermal analysis - determination of the heat capacity of metallic systems. Determination of the viscosity of the material. 4. Discretization schemes. Adjusting under relaxation factors. The convergence criteria. 5. Modelling of solidification of metallic systems. Equation of heat conduction. 6. Natural convection of the melt during the phase change. Solving the heat associated with phase transformations using method of finite differences, finite volumes and finite elements. 7. Microsegregation models. Macrosegregation models. Porosity prediction models. Niyam criterion. 8. Identification of the modeled area. The calculation and selection of heat transfer coefficients. 9. Definition of boundary conditions of simulation of solidification. Determination of the material properties of the modeled system - identification of phase change temperature, enthalpy vs. heat capacity, the dependence of thermodynamic properties on temperature.
