Indagine su alcuni aspetti della resistenza al moto delle chiatte marine

Investigation on some aspects of the towing resistance of Marine Barges The results of a towing experimental investigation on a marine barge model are reported. Our research concerns the bow and stern changes and the length of the middle body; the tests have been performed in different loading conditions. The results obtained, by using the ITTC ’78 correlation line, show the form factor 1 + k and the residual resistance coefficient CR. Such results, properly used, allow useful preliminary considerations about the towing resistance of a barge.
