The Effect of Fishing Basin Construction On the Behaviour of a Footbrdge Over the Port Channel

open access: yesPolish Maritime Research, 2017
The paper analyses possible causes of failure of the rotating footbridge over the Ustka port channel. In July, 2015, strange behaviour of this object was observed in the form of excessive vibrations of bridge platform suspension rods, with the ...

FIV Energy Harvesting from Sharp Edge Square and Diamond Oscillators

open access: yesInternational Journal of Maritime Technology, 2019
The horizontal kinetic energy of the fluid flow, from on-land wind to ocean tidal stream, is one of the most promising sources of the energy. In the field of renewable energies, power extraction from Flow Induced Vibration (FIV) of bluff bodies is a fast

Parametric Study on Wave Interaction with a Porous Submerged Rubble Mound Breakwater Using Modified N-S Equations and Cut-Cell Method

open access: yesInternational Journal of Maritime Technology, 2016
In this paper wave transformation in a submerged sloped breakwater and its hydraulic performance was simulated by developing a numerical model in Fortran. The code was established by combining porous flow and a two-phase model using VOF method.

Effects of Loading Conditions on Hydrodynamics of a Hard-Chine Planing Vessel Using CFD and a Dynamic Model

open access: yesInternational Journal of Maritime Technology, 2017
Planing vessels usually have low ratios of resistance to weight, so they can move fast on sea surface than the displacement or semi-displacement ships. Access to higher speeds is one of the attractions for designers and users.

Time Domain Analysis of the Ventilation around the Partial Immersed Propeller Using Sliding Mesh Method

open access: yesInternational Journal of Maritime Technology, 2017
In this paper a computational method is presented for predicting the unsteady hydrodynamic forces acting on partial immersed propeller (SPP). In order to simulate the unsteady viscous flow around a SPP, a Reynolds-Averaged Navier–Stokes (RANS) solver is ...

A numerical investigation into the crack effects on the natural frequencies of the plates

open access: yesInternational Journal of Maritime Technology, 2014
In the current study, the effect of such parameters as the length, position and angle of crack on free vibrations of a cracked plate was examined by finite element method. The assumed crack was internal and through and its growth was ignored.
