Total resistance analysis on bow form model ulstein X-bow with various angle of flare and stem angle

Abstract

Abstract The current bow form named X-Bow can face waves coming towards the ship by breaking waves more subtly. Based on the Ulstein X-bow design patent, there are provisions such as angle of flare bow and stem angle. Continue the previous research that investigates comparison of total ship resistance between conventional bow and x-bow on ship; this study aims to show the impact from various angle of flare bow and stem angle on total ship resistance by Computational Fluid Dynamic. Results are summarized in tables and graphs, showing that angle variations on the bow with 6° stem and 10° flare has the most optimal ship performance at 14 knots with a total resistance value 383,13 kN compared to the original model of 385,62 kN, which decreased by 0.64%.
