“…The camber ratio is the ratio between the camber (f) at the maximum thickness and the chord length (c) of the propeller blade profile. The camber ratio of 0% to 6% is a common range for NACA airfoils [15]. The camber ratio value of 0%, 1.6%, 2.2 % and 2,8%, as shown in Table 2.…”

The hydrodynamic performance of the B-series propeller can be determined by calculating the polynomial equation published by MARIN. Furthermore, analysis and evaluation of B-series propeller modifications can be done by varying the camber ratio of the foil. The camber ratio affects the lift force on the propeller foil, directly affecting the propeller thrust and torque. Numerical calculations were carried out using Computational Fluids Dynamics (CFD), based on Reynolds Averaged Navier Stokes Equations (RANSE) and turbulence model in the form of explicit algebraic stress models (EASM). The overall results of this study show an increase in efficiency of 4.182 on the foil with a camber ratio of 2.2% when compared to the foil camber ratio of 0%.

In the present study, the correlation between skew angle and blade number on the hydrodynamic performance of a submarine propeller is numerically investigated using computational fluid dynamics. For this purpose, three different blade numbers (3, 5 and 7 blades) and four different skew angles which vary from 0° to 52° are considered based on the INSEAN E1619 propeller model as the main geometry. Three-dimensional numerical simulation is based on Unsteady Reynolds-Averaged Navier-Stokes equations combined with SST k-ω turbulence model. The hydrodynamic coefficients and efficiency are compared against the experimental and numerical results at various advance coefficients (J), and good agreement is achieved. Based on the results, by increasing the blade number, hydrodynamic coefficients are improved. The interaction between 7 blades dissipates the negative wake region in locations near the propeller blades which leads to produce higher hydrodynamic efficiency compared to other propellers. The maximum torque coefficient is generated by the propeller with 7 blades which is enhanced by about 11.8% compared to the propeller with 3 blades at J = 0.88. In addition, lower skew angle gives slightly higher performance than the high skew angle propeller. In overall, hydrodynamic efficiency of the propeller with a skew angle equal to 0° is enhanced by about 19.4% compared to the propeller with skew angles equal to 52° at J = 0.88.
