ENRICHMENT OF HEAVY-WATER IN FLAT-PLATE THERMAL-DIFFUSION COLUMNS OF THE FRAZIER SCHEME INCLINED FOR IMPROVED PERFORMANCE

A separation theory for the enrichment of heavy water in flat-plate th ermal diffusion columns of the Frazier scheme inclined for improved pe rformance has been developed. Equations for the best angle of inclinat ion and maximum separation have been derived. Considerable improvement in separation is obtainable if the columns are inclined at the best a ngle, so that the convective strength can be properly reduced and cont rolled, resulting in suppression of the undesirable remixing effect wh ile still preserving the desirable cascading effect.
