During the guest stay, a validation database for pilot-plant scale bubble columns, which will help to improve the predictive capability of CFD models, shall be build up. For this purpose, experiments at a bubble column at the polytechnic institute of Milan are planned for air/water as well as air/water-ethanol at different operation points using two different gas spargers. The facility is 0.24 m in diameter with a height of 5.3 m. In the past, the cooperation partner already measured the local bubble size distributions and gas holdups for the intended experiments. For a reasonable model validation, however, the liquid velocity is necessary; but a realizable measuring technique was missing. During his doctoral studies, the applicant developed a measuring method with which the measurements are possible, which was tested at the facility in Milan in May this year. The data that will be obtained are not yet published in such a level of detail for large bubble columns and are urgently needed for validation. The results will be published in prestigious international journals and will be provided to other international research groups; further, the results will be the basis for the following cooperation.

在客人入住期间，将建立中试规模气泡柱的验证数据库，以提高CFD模型的预测能力。为此，计划在米兰理工学院的气泡柱上使用两种不同的气体喷射器在不同的操作点进行空气/水以及空气/水-乙醇的实验。该设施直径0.24米，高5.3米。在过去，合作伙伴已经为预期的实验测量了局部气泡大小分布和气体含量。然而，对于一个合理的模型验证，液体速度是必要的；但是缺少一种可实现的测量技术。在博士学习期间，申请人开发了一种测量方法，使测量成为可能，并于今年5月在米兰的工厂进行了测试。将获得的数据尚未以如此详细的级别发布，用于大型气泡列，迫切需要进行验证。研究结果将发表在著名的国际期刊上，并将提供给其他国际研究小组；此外，会议结果将成为后续合作的基础。
