THE EFFECT OF FREEZING RATE ON THE ACCURACY OF NUMERICAL FREEZING CALCULATIONS.

Author(s) : CLELAND A. C., EARLE R. L., CLELAND D. J.

Type of article: Article, IJR article

Summary

THE ACCURACY OF FINITE DIFFERENCE AND FINITE ELEMENT FREEZING TIME PREDICTIONS WAS EXAMINED. THE ACCURACY OF THE PREDICTIONS WAS SHOWN TO DEPEND ON THE RATE OF FREEZING, WITH THE EXTENT OF UNDERPREDICTION INCREASING AS THE RATE OF FREEZING INCREASED. THE ACCURACY OF PREDICTIONS IS LIMITED MORE BY THE PHYSICAL APPROXIMATIONS THAN BY NUMERICAL APPROXIMATIONS. ONLY A MARGINAL IMPROVEMENT, IF ANY, WOULD BE EXPECTED BY ELABORATING THE NUMERICAL SCHEMES. PREDICTIONS TO BETTER THAN + OU -10% APPEAR, THEREFORE, IMPRACTICABLE.
