Waves Investigation of Dynamic Pressure on Wave Screen under Regular

For a cost-effective design of wave screen, an accurate estimation of dynamic pressure and wave force is needed. This study investigates the dynamic pressure action on elements of wave screen. The wave screen consists of several horizontal pipes with constant distance between them. This wave screen provides convection, interchanges of seawater within the harbor district, and makes available wave energy absorption effectively. The experimental were done on regular waves with 3 heights and 6 periods of waves at a constant water depth of 0.6 m. Also 3 difference diameters were considered for wave screen pipes. Dynamic pressures distribution along and around the pipes were measured by the pressure transducers. The results indicated that with increasing of the porosity, the pressure difference was decreased and with increasing of the incident wave height, pressure fluctuation for different porosity was increased. Furthermore, the maximum dynamic pressure fluctuation occurred at the angle more than 45°.
