“…kg Gas (nitrogen) was introduced into HCA through valve V2 in the amount of m 2х = 0.025, 0.05. and 0.075 mol of nitrogen per 1 kg of filled ammonia. This significantly exceeded the predicted accumulation of NCG (in moles) in the loop during long-term operation in orbit [6].…”

“…The value of the diffusion coefficient, which determines the rate of gas dissolution in the supercooled liquid after the condenser, was experimentally assessed. The rate of dissolution depends on the difference in gas concentrations in the bubble and in the liquid, however, the results reported in [6] are not related to the concentration of dissolved NCG in the liquid, which reduces the possibility of their practical use. The presence of NCG in free form can lead to an increase in the hydraulic resistance of chokes and filters; it can block the operation of pumps, heat exchangers and evaporators with capillary-porous structures [7].…”
