Added Resistance & Drift Force Analysis in Regular and Irregular Waves
The sea wave causes excess resistance which is out of scope of calm water resistance. The total wave force in horizontal plane is divided into “Added Resistance” and “Drift Force”. In this study, based on Gerritsma and Beuckelman[3] hypothesis a computer program has been developed for calculation of added resistance and drift force at various ship speeds and various head...
متن کاملCapillary-gravity and capillary waves generated in a wind wave tank: observations and theories
Short water surface waves generated by wind in a water tunnel have been measured by an optical technique that provides a synoptic picture of the water surface gradient over an area of water surface (Zhang & Cox 1994). These images of the surface gradient can be integrated to recover the shape of the water surface and find the two-dimensional wavenumber spectrum. Waveforms and two-dimensional st...
متن کاملAnalysis of hydrofoil craft in regular and irregular waves
In this article, the most important specifications of hydrofoil floats, i.e. their seakeeping under regular and irregular waves under different encounter angles of wave, has been investigated. Numerical simulation has been done using STAR CCM+ software. Surge, heave, roll and pitch motions are kept free at the same time and their effects on each other are taken into account. USV01 model, whose ...
متن کاملStudy of Love Waves in a Clamped Viscoelastic Medium with Irregular Boundaries
A mathematical model is presented to investigate the effects of sandiness, irregular boundary interfaces, heterogeneity and viscoelasticity on the phase velocity of Love waves. Geometry of the problem is consisting of an initially stressed viscoelastic layer with corrugated irregular boundaries, which is sandwiched between heterogeneous orthotropic semi-infinite half-space with initial stress a...
متن کاملNumerical modeling of extreme rogue waves generated by directional energy focusing
Three-dimensional (3D) directional wave focusing is one of the mechanisms that contributes to the generation of extreme waves, also known as rogue waves, in the ocean. To simulate and analyze this phenomenon, we generate extreme waves in a 3D numerical wave tank (NWT), by specifying the motion of a snake wavemaker. The NWT solves fully nonlinear potential flow equations with a free surface, usi...
