SINUSOIDAL PERTURBATION SOLUTIONS FOR PLANAR SOLIDIFICATION.

Author(s) : LI N. Y., BARBER J. R.

Type of article: Article

Summary

A LINEAR PERTURBATION METHOD IS USED TO SOLVE THE TWO-DIMENSIONAL HEAT CONDUCTION PROBLEM IN WHICH A LIQUID, INITIALLY AT THE MELTING TEMPERATURE, BECOMES SOLIDIFIED BY HEAT TRANSFER TO A PLANE MOLD THE TEMPERATURE OF WHICH IS APPROXIMATELY UNIFORM, BUT CONTAINS A SMALL SINUSOIDAL PERTURBATION IN ONE SPACE DIMENSION. RESULTS ARE OBTAINED FOR THE CONSEQUENT SINUSOIDAL PERTURBATION IN THE MELT/SOLID BOUNDARY AS A FUNCTION OF TIME AND FOR THE TEMPERATURE DISTRIBUTION THROUGHOUT THE SOLID SHELL.
