MATHEMATICAL MODELLING OF PROCESS CRUCIBLELESS INDUCTION MELTING OF THE TITANIC ALLOY IN THE NATURAL ATMOSPHERE
By interface of ANSYS and Fluent is developed the numerical model of process of melting of cylindrical billet in a variation electromagnetic field. Calculation process of melting is perfromed by the "enthalpy-porosity" method with application of model of turbulent flows of k-ω SST in non-stationary statement. Electromagnetic sources of the movement and heat were defined by a solution method of final elements of a harmonious task on vector magnetic potential in system "the inductor - billet" on everyone iterations of a hydrodynamic task. On the basis of the constructed model calculation is executed and the analysis of course of physical processes at beztigelny melting of a titanic alloy of BT6 is carried out.
