Research on the Arrangement Process of Marine Submersible Buoy System based on Computational Fluid Dynamics

Abstract

This paper establishes the computational fluid dynamics models of marine submersible buoy system. The models use incompressible Navier-Stokes equations, Renormalization-Group (RNG) turbulence model and the fractional areas/volume obstacle representation method. Using the lumped mass mothed to simulate the anchor line and power supply cable. The result show that the great tension forces increase occurs at the moment when the mooring lines was straightened and after a marine submersible buoy system sinks to the sea floor.
