ShareMODELLING COOLING DOWN OF TUBULAR GEOMETRIES TO CRYOGENIC TEMPERATURES.
Author(s) : REICHEL W., AGSTEN R.
Type of article: Article
Summary
THIS PAPER DEALS WITH THE EXPERIMENTAL STUDY OF THE COOLING PHENOMENA OF PIPES FLOODED WITH LIQUID NITROGEN. THE HEAT TRANSFER COEFFICIENT REQUIRED IS OBTAINED FROM A MODEL OF THE COOLING PROCESS. COPPER, ALUMINIUM, HIGH-GRADE STEEL AND TEFLON PIPES WERE TESTED. THE PIPE LENGTHS WERE 3.73 M AND 34 M (FOR COPPER PIPE), RESPECTIVELY. THE RESULTS OF THE COOLING TIME ARE ILLUSTRATED BY DIAGRAMS THAT ARE SPECIFIC OF THE RESPECTIVE MATERIAL. AN ESTIMATION OF THE COOLING TIME FOR COPPER, ALUMINIUM AND HIGH-GRADE STEEL PIPES OF CONSIDERABLE LENGTHS IS FEASIBLE.
