AbstractThe current research is an extension of a previous study conducted at the University of British Columbia on the effect that specific geometric parameters have on the water discharge rate of a ship opening. This research focuses on open deck ferries and fishing vessels where the collection of water on deck may affect the stability and manoeuvring of the vessel. The geometric parameters affecting the discharge rate, namely the vessel beam, the depth of the water collected on deck, and the height and width of the opening were studied using CFD methods. The effect of each parameter was analyzed by varying the parameter of interest while the other parameters were kept constant. Froude number and non-dimensional discharge time were were calculated using the instantaneous water depth, the water discharge rate, and the opening area as a part of the non-dimensional simulation. The results were compared to the experimental results that were obtained previously at UBC.
