Research Abstract

It will be very important ot estimate the hydrodynamic force acting on a ship for predicting ship manoeuvring characteristics by using mathematical model. This hydrodynamic force depends on especially the ship's form then it needs to estimate the hydrodynamic force acting on ship considering sufficiently with ship's form such as the frame line with high accuracy.
On the hydrodynamic force, we estimated by using the slender body theory, and examined the flow pattern and generation point of free vortex. According to the investigated results, we can estimate the hydrodynamic force acting on a ship by considering with the generation point of free vortex. This generation point of the vortex should be decided as function of the hull form.
Furthermore, this research investigated the cross sectional aspect of round edge effects on cross flow drag acting on rectangular cross section, which are theoretically investigated using of vortex model. From the results of numerical calculations, cross flow drag acting on rectangular cross section decrease abruptly as increasing corner radius, especially for the sections with a breadth to height ratio becoming larger.
