Abstract

Cryogenic liquid hydrogen is easily evaporated at ordinary temperature. The insulation performance of tank is important for liquid hydrogen to be stored and transported safely. Multi-layer insulation (MLI), Vapor cooled shield (VCS), and the degree of vacuum are factors affecting the insulation performance of cryogenic liquid hydrogen tank. In this study, the insulation performance of Cooper conductive shield(CCS), which can replace VCS, is calculated by the CFD method with commercial CFD code STAR-CCM+. The Liquid hydrogen tank is a cylinder structure and has a neck tube forming an outlet of the liquid hydrogen surrounding the inlet. Copper and oxygen-free copper plate is applied instead of a typical VCS and the heat transfer penetrating into inner vessel is evaluated. Three cases of CCS are considered in this study; copper plate; oxygen-free copper plate; non-Cu. It is found that Copper Plate reduces the heat penetration and play the same role as VCS. It conveys the heat to neck tube of liquid hydrogen tank.
