Numerical simulation of propeller open water characteristics using RANSE method

Abstract

The paper presents the results of numerical simulations of propeller open water characteristics by using RANSE method with rotating reference frame approach. The effects of grid type, mesh density and turbulence models on simulation results are analyzed. The well-known Potsdam Propeller PPTC test case is used to verify and validate the accuracy of case studies. At the end, the assessment and recommendation for choosing grid type and turbulence model from the point of view of the level of accuracy are given. The solver used in this study is the commercial package Star-CCM+from SIEMENS. Keywords: Propeller, Open water, Turbulence model, RANSE, Grid type
