The role of fluid compressibility in predicting slamming loads during water entry of flat plates

摘要

This paper presents a numerical and experimental investigation of the water entry of a rigid flat plate. The experimental work was carried out in the Ocean Basin at Plymouth University’s COAST laboratory. An in-house CFD code AMAZON-CW, which is based on a compressible multiphase flow model, was used to simulate the slamming problem. The impact loads on the structure recorded in experiments agree well with the numerical computations. A difference from the impact of sharp , wedge-type bodies, is that the slamming loads exerted on flat plates have pulsations due to the compressibility of fluids.
