ANALYSIS OF THERMAL STRATIFICATION AND SELF PRESSURIZATION IN LIQUID HYDROGEN STORAGE SYSTEMS.

Author(s) : GURSU S.

Summary

BOIL-OFF LOSSES ASSOCIATED WITH THE STORAGE, TRANSPORTATION AND HANDLING OF LIQUID HYDROGEN CAN CONSUME A SIGNIFICANT PORTION OF THE AVAILABLE COMBUSTION ENERGY. SEVERAL MECHANISMS CONTRIBUTE TO THESE LOSSES. THIS PAPER REPORTS ON AN OPTIMIZATION STUDY TO REDUCE BOIL-OFF LOSSES IN CRYOGENIC HYDROGEN STORAGE TANKS. THE OPTIMIZATION TAKES INTO ACCOUNT THE INITIAL HYDROGEN COMPOSITION, TANK SIZE, HYDROGEN LEVEL IN THE TANK, NUMBER OF COOLING STATIONS, AND TANK PRESSURE. OF PARTICULAR INTEREST IN THIS STUDY ARE THE THERMAL STRATIFICATION AND SELF PRESSURIZATION EFFECTS ON THE OVERALL BOIL-OFF RATE.
