Abstract
In our previous study published in 2018, we conducted a theoretical analysis aiming to clarify the cause of the large difference in residual resistance between two model ships with the same form of aft body. The result showed that the large difference is not due to the difference of overall fore body form, but due to only the difference in bow (fore-end) form. We are applying this result to the development of new technologies. In this paper, we discuss two studies we have conducted preparing for the developments. First, we have confirmed the reliability of our previous study result by additional theoretical analysis and by a discussion with related other model test results. Second, we have studied how to manufacture a model for a CWC (Circulating Water Channel): we are developing a new model test method for a CWC using our previous study result. For development, a model is necessary and important. So, we have started the development with the study of model manufacture.
