Pure loss of stability calculation of naval ship in regular waves
The pure loss of stability of a ship is one of the failure modes of the second-generation intact stability criteria. Based on the static surface coordinate system, the generalized pitch angle and draught variable are defined, and a wave equation with ...

Strip calculations for ship oscillation coupled response in regular waves
[Objectives] The strip method is widely used in the sea-keeping design of ships, but the hydrodynamics are only evaluated for the mean-hull position,so heaving,pitching and rolling motions are not essentially coupled. [Methods] For the effective coupling

The high-speed motion of a seaplane involves the coupled hydrodynamic and aerodynamic effects. The suction force, pressure, free surface and motion of the seaplane model were numerically investigated to understand the characteristics of the seaplane's ...

CURRENT DEPTH REFRACTION OF REGULAR WAVES
The complete set of equations for the refraction of small surface gravity waves on large-scale currents over a gradually varying sea bed is derived and presented. Wave lengths, direction of propagation and wave heights are all determined along the so-called wave rays as solutions to ordinary, first-order differential equations.

Due to the interference between the main hull and the outrigger of the pentamaran, resistance is greatly affected. Therefore, research on the pentamaran front outrigger inclination angle has further practical significance for reducing resistance. In this

Nonlinear run-ups of regular waves on sloping structures [PDF]
For coastal risk mapping, it is extremely important to accurately predict wave run-ups since they influence overtopping calculations; however, nonlinear run-ups of regular waves on sloping structures are still not accurately modeled.

Regular and Mach Reflection of Shock Waves [PDF]
The properties that distinguish a shock wave from other waves are that its thickness is negligible compared with other characteristic lengths, and that the state of the medium is changed irreversibly by the passage of the wave. Shocks are therefore a highly nonlinear phenomenon, and parameter changes may be expected to lead to numerous bifurcations.
