- Abstract
In the present research, Computational Fluid Dynamics (CFD) analysis has been conducted to investigate the practical utility of ducted design for marine propellers for a range of Reynolds numbers (Re). Hydrodynamic characteristics are investigated for ducted propeller -Kort nozzle for various duct angles (0o = a = 10o). The Kort nozzle duct section is less explored with NACA hydrofoils and has been a hot research topic in the domain. Here, the hydrodynamic characteristics of the duct section are numerically investigated, considering NACA4415 foil. All the simulations are performed using ANSYS-FLUENT in a range of 1×106 < Re < 5×106. We have used the k-ω SST turbulence model during our investigation. The performance of NACA4415 is evaluated concerning the lift, drag, and pressure coefficient for various angles of attack (-12° < ° < 12°). These models were employed for nozzle configuration at different shroud/duct angles (0° <αd < 10°). It is found that the ducted configuration for the considered hydrofoil performs the best with a duct angle 4° < αd < 6° with respect to hydrodynamic characteristics.
