在Saclay核研究中心（Centre d 'Etudes Nucléaires）、马赛湍流机械研究所（IMST）和海德堡环境物理研究所（Institut für Umweltphysik）的合作下，首次在大型IMST风浪设施中进行了气体交换实验。实验包括同时测量的Rn和He气体交换率，波斜率测量在四个取数，和气泡测量。与以前在较小的隧道中测量的传输速度相比，我们的结果是相当低的。这种效应可以定性地解释为波场的差异，这必须考虑作为气体交换的一个重要参数。在12米/秒的风速下开始的波浪破碎并不强烈。因此，仅获得低的气泡密度，没有显著地增强气体交换。
In a collaboration between the Laboratoire de Géochimie Isotopique (Centre d'Etudes Nucléaires, Saclay), the Institut de Mécanique Statistique de la Turbulence (IMST, Marseille), and the Institut für Umweltphysik (Heidelberg), for the first time gas exchange experiments have been carried out in the large IMST wind‐wave facility. The experiments included simultaneous measurements of Rn and He gas exchange rates, wave slope measurements at four fetches, and bubble measurements. Compared with transfer velocities measured previously in smaller tunnels, our results are considerably lower. This effect can be explained qualitatively by differences in the wave field, which must be taken into account as an important parameter for gas exchange. Wave breaking, starting at 12 m/s wind, was not intense. Consequently, only low bubble densities are obtained, not significantly enhancing gas exchange.
