Abstract

In our previous paper, effect of transom stern bottom profile form on its stern wave resistance has been studied by model tests. Discussion of the model test results has clarified that real stern end immersion at running Ir has a close correlation with the stern wave resistance at the lower ship speed range of F_<rI> < 3.1. Details of the correlation are studied in this paper. For that purpose, an analytical method to estimate the effect of Ir on the stern wave resistance is developed at first. Then, the model test results are analyzed by the method. As a result, it has been clarified that Ir relates with the stern wave resistance mainly through the resistance due to acceleration of water flow at the stern end, one of the four components of the stern wave resistance, at the lower ship speed range.
