Tokyo International Airport (Haneda Airport) is used as a center of a domestic airport in Japan by about 60 million people a year, and is requested to correspond to the increase of the demand in the m...
Free running model test on a large container ship under wind and waves at towing tank
Free running model test large container ship towing tank
2009/4/17
A ship navigating at sea is always suffered from wind and waves. The assessment of the ship speed and thrust under external forces as the wind and waves is important from economical viewpoints. Althou...
Investigation on Broaching-to Using Optimal Control Theory
Broaching Optimal Control Theory
2009/4/10
Broaching-to is a phenomenon in which a ship cannot keep her desired course despite the maximum steering effort. Once this dangerous phenomenon happens, she could capsize due to violent yaw motion. Ge...
Linear forcing for numerical generation of anisotropic turbulence field
Linear forcing numerical generation anisotropic turbulence field
2009/4/9
A new numerical method to generate anisotropic turbulence field in the large eddy simulation was proposed. Based on the assumption that the mean shear is the only external force to maintain the struct...
