Abstract
A comprehensive study has been made for the hydrodynamic analysis of the submarine DARPA 2. The analysis was first performed for hull, then hull with sail on top and then for the complete submarine including hull, sail and appendages. A comparison of tangential velocity and pressure distribution for hull is accomplished using CFD flow solvers and published data. Further, the pressure distribution over the hull with sail is also analyzed. Finally, pressure distribution, forces and moments were calculated over the complete submarine including hull, sail and appendages. Comparison 01 pressure distribution and tangential velocity for the hull show a good agreement with published data. Pressure coefficient comparison for the hull with sail shows the good CFD-CFD agreement. Comparison of Normal force and pitching moment of complete submarine having hull, sail and appendages shows a reasonable agreement with the experimental results of DARPA 2. Both quantitative and qualitative analysis of the complete submarine estimates the required design force and moment at different angles of attack and also demonstrate the flow visualization. (author)
