| Research Abstract |
The series tank test clarified fundamental hydrodynamic characteristics of a single-propeller ship, a twin-propeller ship, and a pod-driven ship having a buttock flow stern with and without skegs in manoeuvring motion. The higher order slender body theory and the thin wing theory, and the computational fluid dynamic technique presented here estimated well these hydrodynamic properties and revealed the mechanism of flow around these ship hull forms.
