Sažetak
Due to interference effects, the resistance of a catamaran is not the same as the double resistance of the monohull. If demihulls are close enough to each other, the wave fields generated by each demihull usually significantly interfere causing either advantageous or disadvantageous effects. In this paper, the numerical investigation of interference effects for the Delft 372 catamaran is performed. The verification and the validation studies are performed demonstrating the potential of the proposed numerical model for the analysis of interference effects. The investigation of the effect of Froude number and demihull separation on the total resistance of a catamaran, trim angle, and sinkage is conducted. The interference effects are quantified through the interference factor, which is defined based on the total resistance of a catamaran and double total resistance of the monohull. Finally, the flow field characteristics, wave patterns, and pressure distributions are analyzed using the Computational Fluid Dynamics.
