COMPARISON OF EXPERIMENTAL TOWING TEST AND CFD ANALYSIS OF SUBMARINE MODEL ON THE SURFACE

Hull form, resistance and powering are need to consider in designing submarine. Submarine hull form is based on the five parameters. The submarine's surface resistance will be importance because of operating at high Froude Number. Model experiment is the most reliable data source on ship resistance determination due to the complication of the flow around the ship's hull. CFD simulation is also carried out for surface condition by FINEMarine and pressure distribution on the hull is appeared. Towing mechanism should be arranged into account in order to fix the pitch motion and to measure hydrodynamic forces. This paper briefs about the towing method and result between model test and CFD. It also includes comparison of wave formation for towing test and CFD.
