Abstract
tures in large scale under realistic conditions. Of particular importance for the design of offshore structures is a realistic representation of the complex superposition of waves and currents, which is currently only possible in a few large-scale test facilities. With the extension of the large wave flume (GWK) in
Hannover to the GWK+, the first test facility of this kind in Germany will be available from 2022. The design and construction of an additional current inlet into a wave channel represents a major technical challenge. The design of the current inlet must ensure that flow conditions similar to those in nature can be reproduced in the study area of the wave channel. As an essential flow component, this paper will therefore describe the development of the current inlet into the extended GWK from the design stage to further optimization by means of a 1:10 model created specifically for this purpose. Insights into the implementation, the flow-related challenges as well as the optimization of the current inlet into the wave flume by means of guiding walls and adjustable guiding vanes, and the general suitability for the approximation of the vertical velocity profile as a 1/15 law are presented.
