Abstract

The analysis of the possible phenomena that take place after the contact between a molten pool and a structure, allows to postulate various kinds of scenarios.
Some of them forecast the formation of a stable solid crust at the interface between pool and structure.
Others do not take into consideration this event.
In the present study, it is hypothized the formation of a stable solid crust, whose extension varies in time, that prevents mixing between fuel and molten material coming from the structure Phenomena that are taken into account are therefore :
- natural convection in the molten pool
- crust formation and growth on pool boundaries
- heat transfer with change of phase in the support structure.
The motion and the energy equations are numerically solved in the assumption of a laminar regime. In this present version the model is therefore applicable to systems with low Rayleigh numbers.
Work is in progress to introduce a turbulence model to analyze more realistic situations.
