EXPERIMENTAL STUDY OF THE SUBLIMATION OF PURE ICE UNDER VERY LOW TEMPERATURE AND RELATIVE HUMIDITY CONDITIONS.

Author(s) : SAKLY M., AGUIRRE-PUENTE J., LAMBRINOS G.

Summary

THE TECHNIQUES OF LIQUEFIED GAS STORAGE UNDER THE ATMOSPHERIC PRESSURE MAINLY RAISE THE PROBLEM OF THE PROTECTION OF WALLS OF UNDERGROUND CAVITIES. THIS PAPER PRESENTS SUBLIMATION TESTS SIMULATINGTHE BEHAVIOUR, ABOVE THE LEVEL OF THE LIQUEFIED GAS, OF AN ICE LAYER IN CONTACT WITH A NON-CONVECTIVE ATMOSPHERE AT VERY LOW TEMPERATURES AND RELATIVE HUMIDITIES. THE TEST PLANT IS A CELL WHERE AN UPWARD TEMPERATURE GRADIENT IS IMPOSED TO A NITROGEN COLUMN, THE ICE SAMPLE, SYSTEMATICALLY MEASURED WITH HIGH ACCURACY, BEING LOCATED AT THE TOP OF THE COLUMN. THE RESULTS OF THE SUBLIMATION RATE DOWN TO 173 K (-100 DEG C) ARE AN APPRECIABLE CONTRIBUTION TO THE PHYSICS OF ICE ANDPROVIDE DATA FOR DEALING WITH THE PROBLEM RAISED AND THE BASIC EQUATIONS OF SUBLIMATION PROBLEMS OF FROZEN DISPERSED MEDIA.
