CFD-Based Estimation of Ship Waves in Shallow Waters

Journal of Marine Science and Engineering
This study examines the evolution characteristics of ship waves generated by large vessels in shallow waters. A CFD-based numerical wave tank, incorporating Torsvik’s ship wave theory, was developed using the VOF multiphase approach and the RNG k-ε ...

Oto-Palato-Digital syndrome in four generations of a large family. [PDF]

, 1986
A new large family, affected by O-P-D syndrome is reported. Nine members in four consecutive generations have been studied. Computerized tomography study of spine and skull showed abnormalities to be confined to mesodermal derivates, while nervous ...

Numerical Study of the Effect of River-Sea Ship Hull Form Parameters on Resistance and Their Optimisation Using the Taguchi-Grey Method

Polish Maritime Research
In this paper, we systematically investigate the effect of the five most important ship hull form parameters, namely the longitudinal centre of buoyancy (LCB), the half angle of entrance of the design waterline ((½))αE), and the length (CLPR), cross ...

Numerical Study of the Hydrodynamic Pressure Field Generated due to Ship Motion at Different Speeds

Journal of Applied Fluid Mechanics, 2020
Ship movement in the shallow seas creates a significant hydrodynamic pressure field about the ship that has effect on the environmental structures such as waterway beds, stationary or moving neighbored vessels, and can also affect marine life. Therefore,
