Description

The main characteristics of a 220 l spherical tank for liquid hydrogen capable to stand a 30 atm operating pressure is described. Thermal insulation is obtained with silicon aerogel. Mechanical stresses and heat losses are calculated. Permanent heat losses reach 10 W and correspond to a daily evaporation of 29 l of hydrogen (13% of the full tank). Initial cooling of the tank leads to the vaporization of about 35 l of nitrogen and 10 l of hydrogen. Losses due to the ortho-para conversion may eventually add up

Abstract (French)

On decrit les caracteristiques principales d'un reservoir spherique de 220 l pour hydrogene liquide pouvant supporter une pression de service de 30 atm. L'isolement thermique est obtenu avec de l'aerogel de silice evacue. On calcule les contraintes mecaniques des enveloppes et les pertes thermiques. Les pertes thermiques permanentes s'elevent a 10 W, ce qui correspond a la vaporisation de 29 l d'hydrogene par jour, soit 13 % du reservoir plein. Le refroidissement initial du reservoir donne lieu a la vaporisation de 35 l d'azote et de 10 l d'hydrogene environ. Les pertes dues a la conversion ortho-para viendront s'ajouter eventuellement.
