| Abstract: | The heat transfer in the insulation jacket will increase immediately after a sudden,catastrophic loss of insulating vacuum(SCLIV) is happened on a HVMLI cryogenic tank.The influence of SCLIV on storage performance in a HVMLI cryogenic tank was experimentally studied in this paper.A test rig was built up and experiments were conducted using LN2 as the test medium.The cryogenic tank was tested in the conditions of various combinations with different initial filling rate and number of insulation layers. |

| Keywords: | HVMLI cryogenic tank Sudden and catastrophic loss of insulating vacuum Insulation layers Initial filling rate |
