This research aims to check the actual performance of the work of the propeller depending on series of results issued from Hamburg basins that are known by RANSE where the arcs analysis and the hydrodynamic characteristics of the propeller work in open water are done by using the commercial program CFD Analysis m by Hydro Comp. Thus, the results were compared with the experimental data and the study of fluently around the different parts of the ship and the definition of resistance values and friction factor CF. These values were compared with those issued by ITTC basins and coincidence was found between those of RANSE and the experimental values in the different stages of study. Therefore, a collection of solutions related to the work of propeller were achieved in addition to the evaluation of the level of interaction and the exchanged effect of the propeller work in different conditions, and the definition of degree of difference resulted from the values of the rotation moment and the factors of advance and control the are resulted from the use of CFD program. The numerical results and the syntheses data were discussed in case of working in open water.
