Abstract

Cogitating flow is investigated around MARINE PROPELLERs, EXPERIMENTALly and numerically. Two different types of conventional model propellers are used for the study. The first one is a four bladed model propeller, so called model A, and the second one is a three bladed propeller, model B. Model A is tested in different CAVITATION regimes in a K23 CAVITATIONs tunnel. The results are presented in characteristic curves and related pictures. Finally, the results are discussed. Model B is investigated based on existing EXPERIMENTAL results. In addition, model B is used for validation of the numerical solution prior to the testing of model A. The CAVITATIONs phenomenon is predicted numerically on a two dimensional hydrofoil, NACA0015, as well as propeller models A and B. The CAVITATION prediction on a hydrofoil is carried out in both steady and unsteady states. The results show good agreement in comparison with available EXPERIMENTAL data. Propeller models are simulated according to CAVITATIONs tunnel conditions and comparisons are made with the EXPERIMENTAL results, quantitatively and qualitatively. The results show good agreement with EXPERIMENTAL data under both cogitating and noncavitating conditions. Furthermore, propeller CAVITATION breakdown is well reproduced in the proceeding. The overall results suggest that the present approach is a practicable tool for predicting probable CAVITATIONs on propellers during design processes.
