Overview

Computational modeling study demonstrates coupled electromagnetic and thermal distributions in an alternating-current submerged electrode system, highlighting a baseline for furnace modeling.

Key Points

Develop and assess a numerical framework for coupled electromagnetic and thermal processes in an alternating-current multi-electrode system representing a submerged arc furnace bath.
Implemented user-defined scalar equations in ANSYS Fluent 2020 R1 for electric potential, magnetic vector potential components, and their time derivatives.
Utilized a two-stage computational scheme where transient electromagnetic equations yield period-averaged Joule heat generation, which serves as the source term in the thermal energy equation.
Evaluated the computational implementation through mesh independence tests, time-step sensitivity analyses, and current and energy balance verifications.
Generated consistent spatial distributions for electric potential, current density, magnetic flux density, Joule heat generation, and temperature throughout the bath.
Demonstrated robust conservation of current and energy balances across the conductive domain without requiring electric arc modeling.
