Simulation of the POW performance of the JBC propeller

The study presents a numerical simulation for the flow around the five-blade model propeller of the Japan Bulk Carrier (JBC hereafter) ship in open water. Computation is performed using the commercial software FineTM/Marine provided by NUMECA where the discretization in space is based on finite volume method using an un-structured grid. The unsteady Reynolds Average Navier-Stokes (RANSE hereafter) equations are numerically solved where the turbulence is modeled by making use of the Explicit Algebraic Stress Model. Three different computational grids were generated for performing a grid convergence test. Results are validated through comparisons with the bench-mark experimental data provided for the Tokyo 2015 Workshop on CFD in ship hydrodynamics held at the National Maritime Research Institute of Japan (NMRI hereafter). Validation of the numerical results proves a reasonable agreement with the experimental data. A special investigation of the wake flow is also provided.
