Flow Resistance Analysis of Submerged Floating Tunnel

  • In order to explore the effects of section shape on pressure distribution,flow field around a submerged floating tunnel for four types of cross section was simulated numerically by using the renormalization group k-ε turbulence model of ANSYS program.Flow field and pressure distribution on the surface of a submerged floating tunnel were analyzed.The results indicate that dynamical pressure has an identical distribution to the same cross section and varies obviously with change in the velocity of ocean stream.Curvature of a submerged floating tunnel is one important parameter influencing the flow field.Ocean stream is separated lately on the surface of a submerged floating tunnel with a streamlined cross section and dynamical pressure on the surface reduces slowly so as to decrease drag force on the surface of submerged floating tunnels with a streamlined cross section.
