Abstract A new method for separating a binary gas mixture, such as hydrogen and carbon dioxide, is proposed and investigated numerically and experimentally. As a pressure driven flow of the mixture goes through a two-dimensional Burgers cascade, the components are separated due to thermal diffusion and the amplifying effect of the cascade. Unlike traditional cascades in isotope separation, active elements like pumps are absent. The device is made thin enough so that the flow and the concentration distribution reaches an equilibrium within each cell. We have observed separation of up to about 9% in hydrogen concentration in our prototype array consisting of over 19,000 cavities placed under a 160-degree temperature difference.

在许多小腔的二维级联中通过热扩散分离二元气体混合物

摘要 提出了一种分离氢气和二氧化碳等二元气体混合物的新方法，并对其进行了数值和实验研究。当混合物的压力驱动流通过二维汉堡级联时，由于热扩散和级联的放大效应，组分被分离。与同位素分离中的传统级联不同，不存在泵等活性元素。该装置做得足够薄，以便每个单元内的流量和浓度分布达到平衡。我们已经观察到，在我们的原型阵列中，氢浓度的分离高达约 9%，该阵列由放置在 160 度温差下的 19,000 个腔组成。
