Four different riser pipe exit configurations were modelled and the flow across them analysed using STAR CCM+ CFD codes.
CFD codes have proven to be a more efficient tool in recent times for simulation of riser design and VIV analyses for risers through CFDs due to its ability to analyse large number of nodes in full-scale simulation [11].
This paper therefore intend to corroborate the present body of knowledge available on the riser design using CFD analysis.
A summary of the physics for the flow simulation in STAR CCM+ is shown in Table 1.
