ABSTRACT
A numerical model is deve lopped to predict solidification delay
in continuous casting. The finite elements method is used in
axisymetric cases to solve the transient thermal problem. The
fluid dynamics pheneomenon is calculated by analytical Blasius
model, adapted to inclinated faces. The coupling algorithm
between the two models evaluates at each non linear resolution
step and at each time step, the solidification front position
and determines the fluid speed vectors which are used to define
the convective term of the heat equation.
INTRODUCTION
In cast iron metal, the liquid metal transfert is generally not
an easy task, because of hight temperature, rapid
solidification, and corrosion contraints.
