Analysis of thermal performance In an industrial furnace using CFD

چکیده مقاله

The Detailed numerical simulations are used to estimate the thermal behavior of an industrial furnace (an aluminum holding furnace) heated by a system of electrical resistances. Estimated temperatures are compared with experimental measurements taken in a real prototype. As a first approach, the symmetry of the geometry is used to reduce the computational resources and only a quarter of domain is initially simulated. Nevertheless the predicted velocities for the flow in the molten load suggest that the patterns induced by the convection effects have a three dimensional behavior. For this reason a new simulation with the full domain is carried out. Both simulations predict almost the same temperatures and energy distributions with different patterns of flow in the molten load. Chaotic behavior is predicted by the full domain approach for the movement
