Helium Conservation by Diffusion Limited Purging of Liquid Hydrogen Tanks
This article is from the 2024 Technical Update. The NASA Engineering and Safety Center (NESC) has developed an analytical model that predicts diffusion between two gases during piston purging of liquid hydrogen (LH2) tanks. This model helps explain dramatic helium savings seen in a recent Kennedy Space Center (KSC) purge, shows that undesired turbulent mixing […]
