Abstract:Aiming at the zero boil-off demand of liquid hydrogen storage tank, this paper uses SAGE software to design and simulate 300 W @ 20 K regenerative heat-driven cryocoolers, verifying the principle feasibility of duplex free-piston Stirling cryocooler and thermoacoustic heat-driven pulse tube cryocooler for the zero boil-off storage of liquid hydrogen. The results show that under the design conditions of mean pressure of 5 MPa, the operating frequency of 50 Hz, the heating temperature of 500°C, and ambient tempe… Show more
