NUMERICAL INVESTIGATIONS OF HYDRODYNAMIC CHARACTERISTICS OF A MARINEFOULED SUBMERGED FLOATING TUNNEL

Marine biofouling is a major concern in the operational performance of submerged floating tunnels (SFTs). Within years after construction, marine growth increases effective dimension and mass SFT hence, can substantially affect hydrodynamic forces alter buoyancy-weight ratio (BWR). Therefore, roughness height one most crucial factors influencing SFT. We investigated effects fouling flow behavior around with varying properties at different Reynolds numbers. Furthermore, cross-section geometry an has significant effect on behavior. In this study, influence increased surface as caused by using Computational Fluid Dynamics (CFD). The created hard main drivers changes (Marty et al., 2021).
