PREDICTION on HYDRODYNAMIC PERFORMANCES of PROPELLER by OpenFOAM

摘要

In this paper the flow around a propeller is simulated by open source CFD tool-OpenFOAM. In order to validate the availability of OpenFOAM code in the field of propeller theory, the steady hydrodynamic performances of DTMB P4119 propeller is predicted. The discrete schemes are second order upwind. The grids are generated by GAMBIT software. The dependence of grid number and adaptability of turbulent model are studied. Compared with the experimental data, it shows that the OpenFOAM code can be used effectively to predict the hydrodynamic performances of the propeller in practice. It can be developed further to study more complex flow phenomena such as cavity flow and other unconventional propulsors.
