ABSTRACT

In this paper an Induction Skull Melting (ISM) system and the induction heating process in the furnace for casting Metallic Fuel Pins (MFP) are considered and simulated numerically using the commercial finite element CFD package FIDAP (Fluent, Inc.). The governing equations are discussed and the solution of these equations with FIDAP is discussed. A segmented-structure of the crucible and how does this kind of structure help to form a "skull" during the fast induction heating process are studied. The induced current is created directly in the "skin" depth of the metal feedstock inside the crucible and the "skin" depth itself serves as the secondary circuit due to the skin effect or Kelvin effect. FIDAP is applied to this system to determine the power deposition profile in electrically conducting region, i.e. the feedstock. The calculated power is subsequently used a source term in the heat equation to calculate the temperature profile in the ISM system.
