Alaska's coastal communities are facing increased coastal hazards. Accurate predictive models are necessary to anticipate how various hazards may affect communities over time. Currently, erosion projections do not take into account the non-linear increase in erosion due to warming near-shore water, air, and permafrost. University of Alaska, Anchorage (UAA) is developing an arctic-capable coastal geomorphic...
A numerical method was developed to study vortex-induced vibration (VIV) on free-spanning marine pipelines. The numerical method uses a partitioned fluid-structure interaction solver with implicit coupling. The method was applied to a baseline model of cross flow around a circular cylinder with structure deformation. Further studies would include the effects of sea flow sediment deposition and scour.
