Abstract

This thesis explores the underlying physics of greenwater overtopping for scenarios of increasing complexity from (i) a fixed rectangular box; to (ii) a fixed box with a bow flare angle; and (iii) a floating rectangular box, using Computational Fluid Dynamics (CFD), supported with additional numerical tools. The results suggest that there is practical value in both CFD and in modifying the classical dam break models to better understand and predict the evolution and damage potential of greenwater. CFD models have the advantage of high resolution, so as to explore aspects of overtopping in detail, whilst dam break models are efficient and can be inserted into existing composite engineering methods to screen large sets of metocean conditions and identify critical design sea states for refined numerical modelling or model testing.
