Convergencia del Método de Elementos Finitos en Problemas de Frontera Móvil

Darío F. Delmastro, Luis E. Juanicó, Alejandro Clausse


A numerical model of a boiling channel based in one-dimensional variable-length finite elements is analyzed. A Galerkin nodal approximation is used to reduce the
conservation equations to a set of ordinary differential equations. The convergence for natural and forced circulation conditions is analytically and numerically studied.
The differences between low and high Froude number conditions are studied, been analyzed the origin of the different discretizations needed to accurately represent
the boiling boundary evolution.
