A Method to Confirm Scale Effect of Stern Waves due to a Transom Stern〔含 Discussion〕

概要

When a ship with a wide immersed transom stern runs on a deeper draft, forward-oriented wave breaking often occurs just behind the transom stern. Stern waves in such condition can be considered to consist of two main components: the forward-oriented wave breaking and remained following waves. Recent studies by the authors have shown that both of the components have scale effect. Experimental confirmation of such results has been partly conducted but is not yet complete. In this paper, the authors have developed a new method, which does not need expensive large-scale similar model ships, for experimental confirmation of stern-wave scale-effect, and have used it for the purpose. As a result, 1) The new method has been clarified to be effective qualitatively at least for the purpose. 2) It has been confirmed experimentally by the new method that the scale effect of stern waves the authors had estimated is qualitatively right.
