Abstract
THE OPERATIONS OF A THERMODYNAMIC VENT SYSTEM (TVS) WILL BE INVESTIGATED WITH THE GOAL OF OPTIMIZING THE PERFORMANCE OF THE CRYOGENIC STORAGE SYSTEM FOR LONG TERM STORAGE. A TEN YEAR STORAGE LIFE IS THE ULTIMATE GOAL TO BE ACHIEVED. THE EFFECTS OF THE VENTED GAS ON IMPROVING THE PERFORMANCE OF A MULTILAYER INSULATION SYSTEM WILL BE OPTIMIZED BY VARIATION OF PARAMETERS. THE OBJECTIVE IS TO MINIMIZE THE HEAT LOAD ON THE CRYOGENIC PRESSURE VESSEL AND THUS MINIMIZE THE CRYOGEN OUTFLOW. THE THERMODYNAMIC CYCLE OF A JOULETHOMSON EXPANSION VALVE IN THE VENT SYSTEM WILL BE SELECTED FOR THE OPTIMAL EFFECT ON THE THERMAL PERFORMANCE. FOR HYDROGEN THE POTENTIAL GAINS IN PERFORMANCE OF THE VENT SYSTEM BY UTILIZING THE ENERGY OF THE PARA-TO-ORTHO PHASE CONVERSION WILL BE INVESTIGATED.
