The numerical solution of a one dimensional, three-phases Stefan problem with a low Stefan number is presented. Joule heating and thermal radiation are demonstrated to be negligible compared to the high power input. The Front Tracking Method is used along with a second order Lagrangian interpolation of the temperature profile near the moving surface defined by the location of the phase change.

Abstract

The numerical solution of a one dimensional, three-phases Stefan problem with a low Stefan number is presented. Joule heating and thermal radiation are demonstrated to be negligible compared to the high power input. The Front Tracking Method is used along with a second order Lagrangian interpolation of the temperature profile near the moving surface defined by the location of the phase change. Results are compared with analytical, numerical and experimental solutions available in literature.
