摘要:
显着的超临界二元液滴成核后,达到幂律的液滴半径的时间增长所需的时间,发现分析和估计在扩散控制或自由分子制度的等温二元蒸汽冷凝。分析了在相同的二元冷凝制度下,二元溶液在增长液滴内的浓度稳定过程。结果表明,设定稳定的液滴浓度在时间上也具有幂律特性。幂律的参数指定为每个制度的二元冷凝,并连接到冷凝蒸汽的热力学和动力学特性,并建立在一个二元液滴的稳定浓度。
英文摘要:
The times required for reaching the power-law-in-time growth of the droplet radius after nucleation of a markedly supercritical binary droplet, are found analytically and estimated at diffusion-controlled or free-molecular regimes of isothermal binary vapor condensation. The process of setting steady concentration in the binary solution within the growing droplet at the same regimes of binary condensation has been analyzed. It has been shown that setting the steady droplet concentration has also a power-law character in time. The parameters of the power law are specified for each regime of binary condensation and are linked to thermodynamic and kinetic characteristics of condensing vapors and to the steady concentration established in a binary droplet.
