The effects of surface roughness as induced by marine fouling on the hydrodynamic forces a submerged floating tunnel (SFT) are experimentally and numerically investigated in detail at Reynolds numbers Re = 8.125 × 103–5.25 104. A sensitivity analysis to different parameters including height, skewness, coverage ratio, spatial arrangement is performed. In addition, an optimized parametric cross-s...

Abstract Submerged floating tunnel (SFT) is a new type of structure across long and deep water straits waterways with good application prospects. The different from the traditional large-span bridges immersed tunnels, which can effectively avoid difficulty under construction foundation in channel, high cost large span bridge, influence typhoons heavy fog et al. severe weather on vehicle driving...

Surface-Piercing Propellers (SPPs) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. Unlike the submerged propellers, theoretical methods have no significant application on simulation of SPPsbecause of problems related to modeling of these propeller...
