Study on the combination of reservoirs and thermal diffusion columns

The heat siphon has long been in general use for the purpose of enriching the isotopes present in a reservoir into a thermal diffusion column. K. Clusius and H.H. Bühler developed an alternative method, the gas oscillator, which they utilized as a gas connecting method. We analyzed both methods mathematically, resulting in the conclusion that the flow rate |σ_R| (g/sec) of the heal siphon and of the gas oscillator should have a value ranging from 3H to 5H, and that the period of the gas oscillator 2T (sec) has little influence on the enrichment process, which permits us to choose a value convenient for operation.
