考虑蒸汽和不可凝结气体的二元混合物与蒸汽的无限平面凝聚相接触的半无限展开式，假设在无限远处有均匀的高速蒸汽向凝聚相流动，并且在凝聚相上发生稳定的凝结。从Boltzmann方程出发，研究了气体混合物的稳态行为。在假定不凝性气体分子与水蒸气分子力学相同的前提下，将该问题归结为两个非线性耦合方程的边值问题：一个是全混合物的非线性问题，相当于前人广泛研究的纯水蒸气的凝结问题；在讨论了问题的一般特征后，给出了数值计算结果。
Abstract A semi-infinite expanse of a binary mixture of a vapor and a noncondens-able gas in contact with an infinite plane condensed phase of the vapor is considered in the case where there is a uniform high-speed flow of the vapor toward the condensed phase at infinity and steady condensation of the vapor is taking place on the condensed phase. The steady behavior of the gas mixture is investigated on the basis of the Boltzmann equation. Under the assumption that the molecules of the noncondensable gas are mechanically identical with the vapor molecules, the problem, which is originally a boundary-value problem of two coupled nonlinear equations, is reduced to two problems of single equations: a nonlinear problem for the total mixture, which is equivalent to the condensation problem for a pure vapor studied extensively by the authors in the previous papers, and a linear homogeneous problem for the non-condensable gas. After the discussion of the general feature of the problem, the numerical computation ...
