Abnormality in Computation of Viscous Resistance of High-speed Hull forms

Abstract

With increase in computational methods and rise in fuel prices, designers need to address a range of parameters so that a vessel may be considered as an efficient design. When 80% of world trade is carried out by sea going vessels, turnaround time in port, manoeuvring characteristics, seakeeping capabilities, bio-fouling and environmental sustainability are some of the several design factors to be considered in the design process. Hydrodynamics of ship design is one area where a few of these considerations can be addressed so that an efficient design is produced. The present research attempts to address a very small segment regarding the power requirements of high speed vessels based on various skin-friction lines and form factors postulated by various authors. In view of this a single model of AMECRC systematic series has been chosen which provides some useful insights to practicing naval architects to determine the calm water resistance characteristics as accurately as possible.
