The results show that the formed olivine and solid solution have the intention to dominate the shrinkage of packed bed below 900 °C, while the formed spinel compounds with higher melting point determine the shrinkage above 1300 °C. In comparison to CO, H₂ has a faster gaseous reduction rate. Therefore, the higher quantity of reduced iron and less disintegration of coke in the packed bed simultaneously suppresses the shrinkage between 900 °C and 1000 °C.

The sloshing behavior and settling characteristics of liquid hydrogen in a large tank with a height of 10.06 m and a diameter of 3.05 m during the coastal period was studied. It is proved that using a single Bond number for similarity scaling is incorrect. A criterion was proposed for evaluating the effect of propellant settling activity, which is described as “Settling is accomplished when the volume fraction of liquid phase in the top region with 10% of the tank height falls below a threshold value”. The results indicated that the settling achieves satisfying effect when the thrust exceeds 8 × 10⁻³ g. The force exerted by the tank on the fluid had a significant impact on the settling performance, which has been overlooked in early studies. Higher initial residual slosh degree leads to shorter settling times.
