摘要

The objective of this research is to model the physics of the separated unsteady viscous flow over the bilge keels of an FPSO hull subject to roll motions. A cell center based Finite Volume Method (FVM) scheme is implemented for the solution of the 2-D Navier-Stokes equations (NS2D). The scheme is verified in the case of a submerged fixed hull with bilge keels subject to alternating flow. The effects on the pressure distribution along the hull and the moment histories are investigated. Moreover, the inviscid flow results are also compared to those from the Boundary Element Method (BEM) based potential solver for verification purposes. Finally, the effects of large roll angle on the FPSO hull with or without bilge keels are presented.
