Abstract:

Liquid-solid mixtures of hydrogen slush hydrogen were produced by vacuum pumping, gaseous He injection with vacuum pumping, and by cooling with liquid He in a low heat leak apparatus that permitted visual observation of the experiments through a periscopic device. The slush H produced by these methods was compressed to a maximum pressure of 1.25 psi and the resulting solid content slush quality was determined by calculation methods. For the compressed slush H produced by vacuum pumping, the quality was generally in the 65 to 85 range, while the compressed quality produced by the He injection with the vacuum pumping method ranged from 55 to 85 depending upon solid formation procedure. The compressed quality for slush H produced by cooling with liquid He generally ranged from 65 to 95 depending on the method of freezing and the time elapsed during the compression. A number of characteristics were noted which varied with the production techniques employed.
