Water collection and discharge from an opening in ships
In this study, experimental results on water collection and discharge from an opening on a floating body at sea are reported. The objectives of the tests were to establish relationships between the geometrical characteristics of an open deck or a damaged hull - its beam, height of the discharge gap (e.g. freeing port)- and wave parameters such as wavelength and wave height. Two separate series of experiments were designed and models constructed for water discharge and collection. A two-dimensional model for water discharge experiments was built to visualize the free surface and to measure the flow discharge from a tank. Additionally, for the study of water collection experiments, a similar plexi-glass model was constructed. This model was used to measure time dependent volume of water accumulation on deck. The amount of water collected inside the plexi-glass tank was measured by four load-cells, at different tank opening heights and wave frequencies and amplitudes.NRC publication: Ye
