Abstract: This paper presents a detailed study on the local pressures acting on the surface of a quasi-rigid cylinder during vertical water entry in to a flat water surface. This water entry event is an approximation of bottom wave slamming of cylindrical structures, which is a typical problem for many naval constructions. Hence, the results from this research can be used during the design of cylindrical structures in a slamming sensitive environment.
The paper shows the impact pressure results of a large set of slamming drop experiments with a cylindrical model, on
a rigorously instrumented test set-up using state
-of-the-art equipment.
The obtained experimental data is compared in detail with
the governing theoretical formulations concerning cylinder slamming. For deadrise angles larger than 4.25°, a good agreement is found with an averaged version of the Wagner theory. This indicates that the Wagner theory is a good estimate for impact pressures acting on a horizontal
rigid cylinder during vertical water entry, for deadrise angles larger than 4.2.
