THE ENTHALPY METHOD FOR HEAT CONDUCTION PROBLEMS WITH MOVING BOUNDARIES.

Author(s) : HUNTER L. W., KUTTLER J. R.

Type of article: Article

Summary

THE PURPOSE OF THE PAPER IS TO DEMONSTRATE HOW AN ENTHALPY METHOD FOR HEAT CONDUCTION PROBLEMS WITH MOVING BOUNDARIES ASSOCIATED WITH PHASE CHANGES CAN BE COMBINED WITH KIRCHHOFF AND COORDINATE TRANSFORMATIONS TO PUT THESE PROBLEMS IN A PARTICULARLY SIMPLE FORM. ALL NONLINEARITIES IN DENSITY, CONDUCTIVITY, AND SPECIFIC HEAT CAN BE CONCENTRATED IN THE FUNCTIONAL RELATION BETWEEN ENTHALPY AND THE GENERALIZED TEMPERATURE. CONVECTION IN THE FLUID IS NEGLECTED. A SIMPLE NUMERICAL EXAMPLE IS INCLUDED.
