EFFECT OF BLOCK SCALE AND REYNOLDS NUMBER ON WAVE FORCE REDUCTION BY WAVE ABSORBING WORKS

Abstract

Effect of block scale and Reynolds number on model experiment of wave pressure in range of breaking wave was examined on an upright sea wall provided with wave absorbing works.
Wave pressure obtained decrease with an increase with following parameters: ratio of incident wave height to block scale, H_I/d', Reynolds number, Re, ratio of width of wave absorbing works to wave length, B/L and ratio of width of wave chamber to wave length, l/L.
The wave force at the upright seawall taken wave absorbing works is P and the wave force without a wave absorbing works is P₀, in addition the ratio of P to P₀, is found between 0.12 and 0.92.
