Summary

Three different pressure rise models were employed to calculate the self-pressurization and boil-off rates. These are a homogeneous model, a surface-evaporation model, and a thermal stratification model. The first two models are based on the assumption that no temperature gradients exist in the tank, while the third one takes the temperature distribution into account. Employing the thermal stratification model, temperature gradients and their effect on the pressure rise rates in liquid hydrogen tank are analyzed. In order to be able to evaluate the performance of the different pressure rise models, the results are compared with experimental data obtained from different tests conducted in the NASA-Lewis Research Center.
