| Abstract Scope |
Computation fluid dynamics simulations were performed to study the thermal stratification and temperature distribution inside an electric arc furnace during flat bath operation. The analysis accounts for the Joule heat generated by the current injected through the graphite electrodes; as well as the thermal losses through both, the bottom surface of the furnace and the cooled side panels. Additionally, the radiative heat transfer is considered. Results indicate that due to Joule heating the bath temperature increases in the center of the furnace. Density difference produces a movement of the bath upward and due to the thermal losses, the bath descends through the furnace walls creating a recirculating convective flow pattern. |
