Description

A numerical heat transfer model for transient conditions in the VAR ingot is used to simulate remelting of zirconium alloys. The model has been validated by comparing its results with macrographic observations on remelted ingots. It can be used to assess the effect of operating parameters, such as electrode melting speed, on the alloy solidification process

Abstract (French)

Un modele numerique des transferts thermiques en regime transitoire dans le lingot VAR est utilise pour simuler la refusion d'alliages de zirconium. Valide par confrontation de ses resultats avec l'observation macrographique de lingots refondus, le modele permet d'evaluer l'effet des parametres operatoires, tels que la vitesse de fusion de l'electrode, sur le processus de solidification de l'alliage
