An Investigation of the Potential Use of Flexible Inflatable Structures as Breakwaters

9521425 Liapis这项研究计划将调查柔性充气结构作为防波堤的潜在有效性。它们的几何、柔韧性和阻尼性将被用来反射或消散相当数量的波浪能量。将考虑两种基本情况：第一种情况，结构用空气充气，并使用系绳系泊在海床上；第二种情况，结构充满水，直接锚定在海床上。研究将包括分析、数值和实验工作，以研究这一复杂的流体相互作用问题。将检查许多参数的影响，例如波的高度和频率、结构尺寸和材料特性、内部压力或水头、系绳长度、方向和材料特性(对于第一种情况)，以及锚固力(对于第二种情况)。将寻求系统参数的最佳组合，以提供最有效的波障。***

9521425 Liapis This research program will investigate the potential effectiveness of flexible inflatable structures as breakwaters. Their geometry, flexibility and damping characteristics would be utilized to reflect or dissipate a significant amount of the wave energy. Two basic cases will be considered: Case I, in which the structure is inflated with air and is moored to the sea bed using tethers, and Case II, in which the structure is filled with water and is anchored directly to the sea bed. The investigation will involve analytical, numerical, and experimental work to study this complex fluid-interaction problem. The effects of many parameters will be examined, such as the wave height and frequency, the structural dimensions and material properties, the internal pressure or head, the tether lengths, orientations, and material properties (for Case I), and the anchoring forces (for Case II). Optimal combinations of the system parameters will be sought, to furnish the most effective wave barrier. ***
