摘要：Data from model tests of an inland waterway vessel in shallow water have been used by the authors to prepare the resistance prediction in full scale.The common ITTC-1978 extrapolation procedure was applied using form factor determined according to the Prohaska method and,separately,by fitting the approximation function to resistance data.At the same time a series of CFD computations of ship flow has been carried out in model scale and in full scale,with double-body model as well as including the effect of free surface.The results of computations were used to determine total resistance and form factor.The values of form factor determined using different methods are similar and relatively high in comparison to values being applied to conventional sea going ships.Resistance prediction according to the ITTC-1978 with form factor was compared to prediction without form factor.The relative difference of resistance amounts 28% at ship speed of 10 km/h and 24% at ship speed of 12 km/h.
