dc.description.abstractPredicting the resistance of a high-speed catamaran has been of interest to naval architects for the last three decades. Even though considerable amount of research has been carried out in this area, there remains a degree of uncertainty in the accurate resistance prediction of catamaran hull forms in the early design stage. Researches carried out so far have generally ignored the resistance characteristics of unconventional and unsymmetrical catamaran hull forms. This thesis attempts to undertake a comparative analysis of resistance characteristics between newly developed unconventional catamaran hull forms of different configurations derived from existing conventional NPL series of round bilge catamaran hull forms (Molland et el 1991). For this a set of catamaran hull forms with the main hull length of 1.6 m, and with a different range of slenderness ratio (L/1/3), B/T ratio are generated by using standard modelling software. The resistance analysis had been carried out by using slender body theory and by using STAR CCM+, a CFD package for Froude numbers 0.25, 0.3, 0.6, 0.8 and 1 respectively and with different separation ratios (s/L) of 0.3 and 0.4. The main objective was to perform a comparative analysis for a wide parameter space which would be encompassing different unconventional hull configurations against conventional hull forms. Literature survey establishes that there is scant literature in public domain to perform resistance analysis on unconventional catamaran hull forms.en_US
