An experimental study on added resistance focused on the effects of bow wave breaking and relative wave measurements

The added resistance is a component that not yet satisfactorily predicted, although its accurate estimation crucial – both from an environmental and economic point of view the design stage ship until operation. One possible sources overprediction occurrence bow wave breaking. first aim this paper to study effect breaking on by combining visual observations with tests. On other hand, as region appears be most dominant contributor resistance, introduces dynamic waterline detection method involving stereo vision. This experimental applied reach second paper, which stress importance relative elevation in ship. By placing rigs inside hull semi-transparent ship, at each momnent time can tracked using edge algorithm. performing tests Delft Systematic Deadrise Series model no. 523, observed proportional height squared. data experiment information necessary reproduce are shared through https://doi.org/10.4121/19525852.
