Waves Investigation of Dynamic Pressures on Wave Screen under Regular

For a cost-effective design of wave screen, an accurate estimation of dynamic pressure and wave force is needed. In 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 and interchanges of seawater within the harbor district, and makes available wave energy absorption effectively. The experimens were done on a wave screen under collision of regular waves with 3 heights and 6 periods of waves at a constant water depth of 0.6 m. Also 3 different diameters were considered for wave screen pipes. Dynamic pressures distributions along and around the pipes were measured by the pressure transducers. The results indicated that with increasing 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 was occurred at the angle more than 45°.
