How Targeted Cryogenic Cooling Reduces Heat Ingress into Liquid-Hydrogen (LH2) Tanks

Caption

In simulations of a KRISO-designed Type-C tank, structural supports accounted for more than 85% of total heat ingress in the baseline configuration. Targeting these thermal bridges, and the head–shell junction, with cryogenic-fluid channels produced the largest reductions in heat ingress: 43.6% with LNG and 66.5% with LN2. These values are specific to the modeled tank and operating conditions.
