Summary

THE AXIAL TEMPERATURE INCREASE EXPERIENCED BY THE COOLANT GIVES RISE TO TWO-DIMENSIONAL FREEZING ABOUT THE TUBE. IN THE FIRST PART OF THE PAPER, THE PROCEDURES USED TO INCORPORATE THE COOLANT ENERGY EQUATION AND THE VARIOUS BOUNDARY CONDITIONS INTO THE SOLUTION METHODOLOGY ARE DESCRIBED. A CLOSED-FORM ANATYTICAL SOLUTION IS THEN DERIVED TO START THE MAIN NUMERICAL SOLUTIONS. THE NUMERICAL WORK WAS FOCUSED ON GASEOUS COOLANTS. RESULTS WERE OBTAINED FOR THE THICKNESS OF THE FROZEN LAYER,THE COOLANT BULK TEMPERATURE, THE TUBE WALL TEMPERATURE, AND THE ENERGY EXTRACTED FROM THE PHASE-CHANGE MEDIUM, WITH THE COOLANT STANTON NUMBER, THE BIOT NUMBER, AND THE SOLIDPHASE STEFAN NUMBERS AS PARAMETERS. AMONG THE PARAMETERS, THE RESULTS WERE NOT VERY SENSITIVE TO THE STANTON AND STEFAN NUMBERS BUT WERE QUITE RESPONSIVE TO THE BIOT NUMBER.
