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. ***

[9521425 . Liapis]这个研究项目将调查柔性充气结构作为防波堤的潜在有效性。它们的几何形状、灵活性和阻尼特性将被用来反射或消散大量的波浪能量。将考虑两种基本情况：第一种情况是，结构体充气并使用绳索系泊在海床上；第二种情况是，结构体充满水并直接锚定在海床上。调查将涉及分析，数值和实验工作来研究这个复杂的流体相互作用问题。将检查许多参数的影响，如波浪高度和频率，结构尺寸和材料特性，内部压力或水头，锚索长度，方向和材料特性（情况一），以及锚固力（情况二）。将寻求系统参数的最佳组合，以提供最有效的波障。＊＊＊
