LARGE-SCALE SLUSH-HYDROGEN-PRODUCTION EXPERIMENTS.
Abstract
This is the first of a series of reports on tests of the Air Force slush-hydrogen facility. This information is concerned with results of production and mixing experiments. During the first month of testing, liquid hydrogen was used but later tests used liquid nitrogen because a number of modifications to the apparatus were necessary and because of safety considerations. The experiments were trial-and-error runs on a variety of pumping and mixing combinations. The mixer configuration was changed at intervals in an effort to improve slush production. A mixer configuration was derived which produced a satisfactory slush. This final design consists of a rake assembly at the liquid surface to break the crust and a paddle assembly toward the bottom of the tank to stir the solids. The final configuration not only provided a continuous process in which crust was prevented from forming, but also provided a large amount of settled slush in a relatively short period of time. Experiments will be continued to optimize the technique and to determine particle characteristics. (Author)
