Mathematical Simulation of Falling Liquid Film Condenser for Removal of Helium and Separation of Hydrogen Isotopes

摘要

The present paper reports the extension of our previously reported work on mathematical simulation of a falling liquid film condenser. The mathematical model is fully described and its convergence characteristics are explored in detail. More concise parametric studies are made considering the low tritium concentration in the top gas the first priority desired. The gas mixture of 50 - 50 D-T containing 1% H and 5% He is continuously fed to a point near the lower end of the sufficiently long packed section and separated into two streams: the helium gas containing --10% H sub 2 -HD, and the liquid hydrogen isotopes containing 0.01 ppm He. The operating pressure is about 5 atm. (Atomindex citation 14:750743)
