2．Field of Teaching and Research

The educational programs are hydrostatics, resistance, propulsion, wave loads, motions and design of a ship. The field of research is theoretical, experimental and numerical marine hydrodynamics.

3．Research Themes and Equipment

 a． Model Resistance Test for a High-Speed Vessel
Resistance and attitude test for a high-speed model boat (Fig.1) has been conducted in a high-speed circulating water channel (Fig.2). A trim fixed type of dynamometer especially devised for a high-speed model boat is used.

The circulating water channel with a maximum speed 2.5 m/s is used not only for research but also for educational student experiments.

b．Active Wave-Absorbing Wave-Maker System
A wave-tank has been used for the experiments of wave-loads and wave-induced motions of a ship or a marine structure. The wave-tank has a plunger type of wave maker controlled to absorb the reflected waves.

ｃ．Computational Fluid Dynamics (CFD)
CFD, new Finite Analytical Methods (FAM) especially, has been studied to get a computational method with high accuracy and high stability. This numerical flow analysis method will be developed to a ship hull form.
