Abstract

The convergence properties of several non‐linear solution procedures were examined with respect to the accelerated flow of a fluid in a converging channel (the Hamel problem), using two different finite element computer programs with different elemental construction. The Reynolds number varied from that for creeping flow to 1088 without exceeding the radius of convergence. Special attention was given to the successive substitution and Newton–Raphson solution algorithms, with a significant advantage in rate of convergence noted for the latter.

A finite element, thermally coupled incompressible flow formulation considering phase-change effects is presented. This formulation accounts for natural convection, temperature-dependent material properties and isothermal and non-isothermal phase-change models. In this context, the full Navier -Stok
