Abstract

For a cost-effective design of wave screen, an accurate estimation of dynamic pressures and wave forces is needed. This study investigated the acting dynamic pressure on elements of wave screen consist of horizontal pipes with constant distance between them. This wave screen can be beneficial for convection and interchange of seawater within the harbor district and, furthermore, perform wave absorption effectively. The physical experiments were performed by considering regular waves under 3 heights and 6 periods of waves and 3 diameters of pipes wave screen. The tests were carried out for 0.6m still water depth value. Dynamic pressure distribution along and around pipes was obtained employing pressure transducers. The experimental results indicated that increasing the porosity decrease pressure difference and with increasing the incident wave height for different porosity increase pressure difference. Furthermore, the maximum dynamic pressure difference does not often occur at the section normal to the wave direction.
