Abstract
Small-Waterplane-Area Twin Hull, commonly known as SWATH, is a catamaran ship concept featuring cylindrical hulls resembling torpedoes. This concept is designed and applied with the aim of enhancing ship performance by improving stability. It is believed that the design reduces wave resistance due to the small surface area and streamlined shape of the supporting deck and hull. This study focuses on the resistance characteristics of SWATH components, specifically the struts, with variations in inclination angles (inclined struts). The configurations include four inclination angles for the struts: 10˚, 20˚, 30˚, and 40˚. Additionally, four ship speeds are examined Fn: 0.316, 0.422, 0.633 and 0.844 for each inclination angle. The calculations and analysis in this study utilize the Computational Fluid Dynamics (CFD) method through the Ansys Fluent software. The findings reveal that increasing the inclination angle of the struts progressively reduces the total resistance of the ship. Similarly, inclined struts with larger inclination angles reduce the wave resistance coefficient, contributing to a decrease in total resistance. However, the frictional coefficient exhibits fluctuating increases and decreases across different inclination angles. A notable reduction in resistance, reaching up to 13%, is observed at a strut inclination angle of 40˚ compared to 0˚. It can be concluded that inclined struts effectively reduce the resistance of SWATH ships, achieving relatively optimal performance across all speeds. This study provides insights into the impact of strut inclination angles on SWATH ship resistance and contributes to the development of more optimized SWATH concepts. Keywords: Small-Waterplane-Area Twin Hull (SWATH), Inclined Strut, Resistance
