Abstract

The pumping characteristics of liquid-solid mixtures of parahydrogen (slush hydrogen) are of considerable interest, since its use as a rocket propellant could require that it be pumped in ground installations and space vehicles. No previous work on pumping slush hydrogen has been reported, but extrapolation of relationships for pumping water slurries [1] indicates that the pumping characteristics of liquid and slush hydrogen should be the same when the difference in density is considered. This contrast to water slurry behavior is due to the similar flow losses for liquid and slush hydrogen.
