Sažetak
The verification of the previous ballast flow calculation was successfully conducted. The calculation was performed independently once again and the results were compared. The comparison showed that the butterfly valve and intake pipe were chosen correctly. This report presented in detail the calculation procedure and supported it with 2D flow simulation results. These simulations indicate the zones of high vorticity and the influence of the asymmetrical sea-chest design on the flow patterns. Two simple design improvements were suggested which would lower the flow resistance in the tank intake system and therefore shorten the time intervals needed for filling up the ballast tanks.
