Abstract

Kort-nozzle propellers are used for the tugs, trawlers and other vessels in which are working in heavy conditions. Thrust is generated by propeller and duct. In order to evaluate the propulsive performance of the Kort-nozzle propeller, a Reynolds-Averaged Navier Stokes (RANS) solver is employed. Kort-nozzle propeller is selected by Kort-nozzle propeller with 19A nozzle. The Kort-nozzle propeller is analyzed by three turbulence models of the k-ε standard, k-ω SST and RSM. The numerical results are compared with experimental data. Hydrodynamic characteristics are presented and discussed.
