The field measurements performed in the Port of Ghent in 2020 are used as basis (i.e. prototype) for the physical scale model research. The prototype dimensions have been scaled down to an appropriate scale and a systematic variation of the key parameters were performed, aiming at characterizing the three-dimensional flow field originated by a jet reflected on a vertical wall resulting from a bow thruster. The main goal of the scale model tests is to improve the general understanding of the flow behavior, and to create a benchmark dataset for validation of CFD models.

Timeline
In 2020 field measurements were performed in the Port of Ghent. The scale model tests have started in 2021 and continued in 2022. The final physical scale model measurement report, including analysis of the results and comparison to existing design guidelines, has become available in 2023. Also the report on detailed numerical model simulations has become available in 2023.

The physical scale model dataset that has been obtained within this research project is extensive and characterizes flow induced by a transverse bow thruster in very high detail. The data can therefore be used as a benchmark for numerical model validation and further optimization of design guidelines for bed protections. The research shows that highest flow velocities occur for smallest wall and underkeel-clearances. Present design guidelines predict the magnitude of max. maximum horizontal velocity near the bed well for most tested situations, however farther away from the quay wall guidelines seem to be overly conservative, providing room for optimization of bed protections.
