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 کاملOrbital evolution around irregular
The new prooles of the space missions aimed at asteroids and comets, moving from y{bys to rendez{ vous and orbiting, call for new spaceeight dynamics tools capable of propagating orbits in an accurate way around these small irregular objects. Moreover, interesting celestial mechanics and planetary science problems, requiring the same sophisticated tools, have been raised by the rst images of as...
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 کاملVorticity and Divergence of Surface Velocities Near Shore
The nearshore environment is complex, with many competing dynamical elements. Surface waves and edge waves (a form of surface wave trapped to the shore) can generally be separated from other forms of motion because of their fast propagation speeds. However, other motions such as internal waves, shear waves, density flows, and isolated vortex pairs can move at comparable speeds. A tool to help s...
متن کاملorbital doppler evaluation of blood flow velocities in optic neuritis
purpose : to evaluate orbital blood flow velocities and optic nerve diameter with doppler and gray-scale sonography in patients with acute unilateral optic neuritis (on) methods : orbital doppler and gray-scale sonography was performed in 46 eyes of 23 patients aged 19-47 with acute unilateral on. on was diagnosed by an ophthalmologist on the basis of clinical presentation, presence of decrease...
