摘要：The wave dissipating performance of air bubble breakwaters with different layouts is studied by experimental and numerical methods in this article Based on the assumpation that the mixture of air and water is regarded as a variable density fluid, the mathematical model of the air bubble breakwater is built The numerical simulation results an compared with the experimental data, which shows that the mathematical model is reasonable for the transmission coefficient Ct(m) The influencing factors are studied experimentally and numerically, including the incident wave height H(i), the incidentt wave period T, the air amount Q(m), the submerged pipe depth D and the single or double air discharging pipe structure Some valuable conclusions are obtained for further research of the mechanism and practical applications of air bubble breakwaters
