dc.description.abstractAlthough catamarans continue to increase in size and application with bigger and better designs than the present generation, trimaran and multi-hull forms for high-speed operation are a recent phenomenon due to speed of turnaround time and payload. To fulfill the stringent requirement for commercial and military transportation, various versions of optimum design are being undertaken recently. In particular, the high-speed ferry industry is presently looking at novel hull forms such as the form of trimarans and pentamarans which are considered in one of the most affordable hull forms for high-speed operation around the world. However, few published articles are in existence regarding resistance of trimaran hull forms. This research conducted a CFD analysis of wave resistance for trimaran hull forms as a parameter range of practical hull forms is established round bilge trimaran hull forms based on the NPL systematic series. The wave resistances of high-speed trimaran hull forms are therefore, estimated by using ANSYS FLUENT, a commercial CFD software package. To begin with, a systematic series of round bilge demi-hulls are generated, and their wave resistances in calm water are determined by using ANSYS FLUENT to briefly examine nature and degree of reliability of ANSYS FLUENT. The primary aim of this investigation is to determine wave resistance characteristics of slender round bilge configurations of trimaran hull forms in the high-speed range corresponding to Froude numbers up to 1.0. Model test results obtained from the Ship Science Report (71) have been used to verify the efficacy of the CFD analysis. The results obtained from CFD have shown considerable promise, and form factors of trimaran hull forms in calm water can be seen as achievable.en_US
