VDM Shen, M: Interaction of Ocean waves and Offshore Structures

INTERACTION OF OCEAN WAVES AND OFFSHORE STRUCTURES is that frequent phenomenon when artificial breakwaters are built for protecting coastal zone or natural bottom is formed by energetic sea state. With spectral and statistical agreement of realistic sea state, Mao-Lin Shen provide a numerical environment to identify phenomena which are difficult to be observed in field data or experimental outcome. Rigorous fluid mechanics were applied so that fluid visualization is possible and showed by flow field. Differ from traditional work, which can only visually recognizes vortices, Mao-Lin Shen establishes a process to auto-recognize vortex region, and thus vortex strength and location of vortex center have been identified scrupulously. By analyzing the vortices around submerged breakwater and above ripple bed, momentum transfer and nutrition distribution can be further quantified.
