What is it about?
Cylindrical structures are present in so many contexts, from oil platforms to offshore wind turbines. In our work, we evaluated how to control the water flow around these structures, modeled as 3D bodies where end effects (due to the tip of the bodies) were present. More specifically, we investigated how a technology with no power input could affect the flow around a submerged body and another, which was located just below the water surface.

Why is it important?
Most models we have found in the literature are 2D and therefore do not represent the actual flow around the body with the passive mechanism we just investigated. Even less common is to consider a free water surface such as ours. Experiments are difficult to conduct and often provide results that are limited compared with simulations. With our simulations, we were able to not only represent 3D bluff bodies, but also understand how the suggested mechanism acted on the flow.
