Modelling of electromagnetic heating and mixing conditions in glass melt output equipment

V. Geža; Andris Jakovics; Uwe Dipl.-Ing. Krieger; Bernd Halbedel

Purpose – The purpose of this paper is to investigate the outlet of a special glass melting system, which is used to control melt flow and modify flow pattern.Design/methodology/approach – Numerical calculations in ANSYS and ANSYS CFX were used to study electromagnetic, thermal, hydrodynamic and chemical mixing processes, results are validated by comparison with experimental data.Findings – Obtained results show that investigated approach can improve glass melt chemical homogeneity significantly – Lorentz force driven melt movement in conjunction with diffusion process ensures good mixing quality.Research limitations/implications – The mixing in glass melt is present only in azimuthal direction (in cylindrical coordinate system associated with outlet tube axis) but the radial homogenization is determined by diffusion only.Practical implications – The experiments in JSJ GmbH with soda lime glass were successful and showed mixing effect in output material, thus providing additional method for glass producti...
