Nowadays, the use of ships and boats with small propeller clusters is becoming more and more popular. Based on the geometry of the propeller, follow the Suzuki DF 9.9 apart from previous studies, in this article, we will apply OpenFOAM, an open source software to carry out reverse engineering of the performance of the Suzuki DF 9.9’s propeller. This is a 3-blade propeller with dimensions of 225×205 mm. Due to the popularity and widely used in today's industry, the kepsilon model will be selected for use in our simulations. The simulation’s results will be evaluated and compared with the experimental results that have been implemented before. So, the application of the numerical analysis of the Suzuki DF 9.9’s performance could provide consumers with valuable reference in selecting the appropriate gear ratios when the an electric motor is used instead of the four stroke 9.9 hp outboard motor.
