Experimental and Computational Analysis of the Ship Propeller in Open Water Conditions for Inclined Flow

摘要

The paper presents the results of computational analyses simulating the open water tests of ship propeller in inclined flow. The results of computations are compared with the results of corresponding experimental analyses carried out in the towing tank of Ship Design and Research Centre CTO S.A. The object of the research was the model propeller identified as CP469. The aim of the study was to validate the results of numerical simulations performed at model scale. The computational analyses were carried out at model scale with the use of two computational models: Reynolds-Averaged Navier-Stokes model implemented in Star CCM+ software and lifting surface model, implemented in the in-house code. The numerical simulations and experimental studies were carried out for exactly the same load conditions of the propeller. The work is part of a series of activities aimed at the development of advanced numerical methods supporting the design process of ship propellers with taking into account their actual operating conditions.
